To efficiently manage and format JSON data within VS Code, leveraging its built-in capabilities and powerful extensions is key. Here’s a quick guide to prettify JSON in Visual Studio Code:

  1. Open your JSON file: Simply open any .json file or a file containing JSON content (like a .js file with a JSON object) in VS Code.
  2. Use the built-in formatter:
    • Right-click: Right-click anywhere in the editor window and select “Format Document” or “Format Selection“.
    • Keyboard Shortcut: The quickest way is to use the prettify json vscode shortcut.
      • On Windows/Linux: Shift + Alt + F
      • On macOS: Shift + Option + F
    • Command Palette: Open the Command Palette (Ctrl + Shift + P or Cmd + Shift + P), type “Format Document”, and select it.
  3. Ensure JSON Language Mode: VS Code usually auto-detects .json files. If you’re working with JSON embedded in another file type, ensure the language mode in the bottom-right status bar is set to “JSON” for optimal formatting.
  4. Install a dedicated json beautifier extension vscode (Optional but Recommended): While VS Code has a native formatter, extensions like “Prettier – Code formatter” or “Pretty JSON” offer more robust configurations and validation.
    • Go to the Extensions view (Ctrl + Shift + X or Cmd + Shift + X).
    • Search for “Prettier” or “Pretty JSON”.
    • Click “Install”.
    • Once installed, you might need to set it as your default formatter for JSON files in VS Code settings. Go to File > Preferences > Settings (or Code > Preferences > Settings on macOS), search for “Default Formatter”, and select your preferred extension.

This streamlined process ensures your JSON is consistently readable and well-structured, making development much smoother. Whether you prefer the format json extension vscode built-in feature or a dedicated pretty json extension vscode tool, VS Code has you covered.

Mastering JSON Formatting in VS Code: A Deep Dive into Efficiency

In the world of web development, APIs, and configuration files, JSON (JavaScript Object Notation) is ubiquitous. However, poorly formatted JSON can quickly become a labyrinth of unreadable data. Visual Studio Code, with its robust ecosystem, offers powerful tools to prettify JSON, transforming convoluted strings into clear, structured, and human-readable formats. This isn’t just about aesthetics; it’s about boosting productivity, reducing errors, and facilitating collaboration. Let’s delve into how you can truly master JSON formatting in VS Code, moving beyond basic prettification to a truly optimized workflow.

The Inherent Power of VS Code’s Built-in JSON Formatter

VS Code isn’t just a text editor; it’s a feature-rich IDE that comes with native support for JSON. This means right out of the box, you have powerful formatting capabilities at your fingertips, requiring no additional installations. For many users, this built-in formatter is more than sufficient, offering reliable and consistent results for the vast majority of JSON documents. It adheres to the JSON specification, ensuring that your formatted data remains valid.

Latest Discussions & Reviews:
  • Format Document: This command (Shift + Alt + F on Windows/Linux, Shift + Option + F on macOS) will take the entire content of your active JSON file and apply the default formatting rules. This is ideal for quickly cleaning up a whole file.
  • Format Selection: If you only need to format json extension vscode a specific snippet of JSON within a larger file, select the relevant lines and then use the same shortcut. This is particularly useful when you’re working with embedded JSON strings in JavaScript or TypeScript files.
  • Command Palette: For those who prefer typing commands, Ctrl + Shift + P (or Cmd + Shift + P) opens the Command Palette. Type “Format Document” or “Format Selection” and hit Enter. This provides a clear, textual way to invoke the formatting.

Understanding VS Code’s Default JSON Settings

VS Code’s built-in JSON formatter is highly configurable. You can adjust settings to control indentation, line endings, and more.

  • Indentation: By default, VS Code uses 4 spaces for JSON indentation. You can change this globally or per workspace. Navigate to File > Preferences > Settings (or Code > Preferences > Settings on macOS), search for json.format.insertSpaces (boolean) and json.format.tabSize (number). Setting insertSpaces to false will use tabs, and tabSize determines the width of the tab.
  • Validation: VS Code also offers real-time JSON validation, highlighting syntax errors as you type. This is crucial for catching malformed JSON before it causes runtime issues. The errors typically appear as red squiggly lines and are listed in the “Problems” panel.
  • Schema Support: A less known but incredibly powerful feature is VS Code’s support for JSON schemas. By associating a JSON file with a schema, you get intelligent auto-completion, hover information, and stricter validation tailored to the schema’s definition. This transforms JSON editing from a manual task to a guided experience. For instance, if you’re editing package.json, VS Code automatically applies the appropriate schema for Node.js projects, providing context-aware suggestions.

Enhancing Workflow with Dedicated JSON Extensions

While VS Code’s native formatter is robust, dedicated json beautifier extension vscode tools like “Prettier – Code formatter” or “Pretty JSON” often provide more granular control, advanced features, and a more consistent formatting experience across different file types. These extensions are particularly valuable in team environments where maintaining consistent code style is paramount. Things to do online free

Prettier – The Gold Standard for Code Formatting

Prettier is arguably the most popular and widely adopted code formatter. It’s an opinionated code formatter that enforces a consistent style by parsing your code and re-printing it with its own rules. This means less time debating style and more time writing code.

  • Installation: Open the Extensions view (Ctrl + Shift + X or Cmd + Shift + X), search for “Prettier – Code formatter” by Esben Petersen, and click “Install”.
  • Setting as Default: After installation, it’s recommended to set Prettier as your default formatter. Go to File > Preferences > Settings, search for “Default Formatter”, and select “Prettier – Code formatter”. You can also enable “Format On Save” (editor.formatOnSave) to automatically pretty json extension vscode your files every time you save, a massive productivity booster.
  • Configuration: Prettier is “opinionated,” but you can customize some aspects. Create a .prettierrc file (e.g., .prettierrc.json or .prettierrc.js) in your project root. Common settings include:
    • "tabWidth": 2: Sets indentation to 2 spaces.
    • "useTabs": true: Uses tabs instead of spaces.
    • "printWidth": 120: Defines the maximum line length before Prettier wraps code.
    • "trailingComma": "es5": Adds trailing commas where valid in ES5.
    • These configurations ensure that prettify json extension vscode operations align with your project’s specific style guidelines.

Pretty JSON – A Specific JSON Enhancer

For those who prefer a tool specifically focused on JSON, the “Pretty JSON” extension by Dan Lew provides specialized features.

  • Installation: Search for “Pretty JSON” in the Extensions view and install it.
  • Key Features:
    • Prettify/Minify: It allows you to toggle between prettified and minified JSON formats. Minified JSON is useful for production environments to reduce file size, while prettified JSON is for development and debugging.
    • Sort Keys: A unique feature is the ability to sort JSON object keys alphabetically, which can be incredibly helpful for comparing JSON files or maintaining consistent ordering.
    • Copy/Paste: Provides quick commands to copy prettified JSON or paste and format directly.
  • Usage: After installation, you can access its commands via the Command Palette (e.g., “Pretty JSON: Prettify JSON”).

Advanced Techniques for JSON Management in VS Code

Beyond basic formatting, VS Code offers advanced capabilities for managing JSON data, transforming it from a simple text file into a dynamic, interactive component of your development workflow. These techniques are particularly beneficial for developers dealing with complex data structures, large API responses, or intricate configuration files.

Working with JSON Schemas for Enhanced Productivity

JSON Schema is a powerful tool for describing the structure of JSON data. VS Code’s native support for JSON Schema significantly enhances the editing experience, providing auto-completion, validation, and hover information. This makes it easier to format json extension vscode correctly from the outset and prevents common data entry errors.

  • Linking a Schema: You can link a JSON file to a schema using the $schema property at the root of your JSON document: 
    {
  "$schema": "http://json.schemastore.org/package",
  "name": "my-app",
  "version": "1.0.0"
}

    VS Code will automatically fetch and apply the schema, offering intelligent suggestions as you type. For example, when editing package.json, VS Code uses the package.json schema to provide relevant fields like dependencies or scripts.

  • Custom Schemas: You can also define your own custom JSON schemas for internal data structures or configurations. In your VS Code settings (settings.json), you can map file patterns to specific schema files: 
    "json.schemas": [
  {
    "fileMatch": [
      "**/config.app.json"
    ],
    "url": "./schemas/app-config.schema.json"
  }
]

    This ensures that all config.app.json files in your project are validated against your custom schema, making sure they always conform to the expected structure. This proactive validation significantly reduces bugs caused by malformed configuration.

Leveraging Multi-Cursor Editing for Quick Adjustments

Sometimes, you need to make the same change across multiple lines of JSON, such as adding a common field or changing a value. VS Code’s multi-cursor editing is incredibly powerful for this. Reverse binary calculator

  • Adding Cursors:
    • Alt + Click (Windows/Linux) or Option + Click (macOS) to place multiple cursors.
    • Ctrl + D (Windows/Linux) or Cmd + D (macOS) to select the next occurrence of the current selection, adding a cursor.
  • Practical Example: Imagine you have an array of objects and need to add a status field to each. You can select the end of the line for the first object, then use Ctrl + D repeatedly to place cursors at the end of subsequent objects. Then, type , "status": "active", and the change will apply to all lines simultaneously, making prettify json extension vscode much faster than manual editing.

Using VS Code’s Find and Replace with Regular Expressions

For complex transformations or data cleanup within JSON, VS Code’s Find and Replace functionality, especially with regular expressions, is invaluable.

  • Open Find/Replace: Ctrl + H (or Cmd + H).
  • Enable Regex: Click the .* icon in the Find widget to enable regular expressions.
  • Example Use Case: Suppose you have a large JSON file where all boolean values are represented as “True”/”False” strings instead of actual true/false booleans.
    • Find: "(True|False)"
    • Replace: \L$1 (This converts the matched group to lowercase, so “True” becomes “true” and “False” becomes “false”).
      This regex-based replacement is a game-changer for large-scale data cleansing and ensuring JSON validity without manual, error-prone edits.

Automating JSON Formatting with Task Runners and Git Hooks

For teams and projects where consistent prettify json extension vscode is non-negotiable, integrating formatting into your development pipeline through task runners and Git hooks provides an automated safety net. This ensures that all JSON committed to your repository adheres to your defined style guidelines, reducing manual review time and preventing “style wars.”

Integrating with npm Scripts or Gulp/Webpack Tasks

You can incorporate JSON formatting into your project’s build or development scripts using tools like npm (Node Package Manager) or task runners such as Gulp or Webpack.

  • Using Prettier CLI with npm scripts: If you’re using Prettier, its Command Line Interface (CLI) can be integrated directly into your package.json scripts.
    1. Install Prettier: npm install --save-dev prettier
    2. Add Script: In package.json, add a script like: 
      "scripts": {
  "format": "prettier --write \"./**/*.json\"",
  "check-format": "prettier --check \"./**/*.json\""
}
    • npm run format: This command will format all JSON files in your project, overwriting them with Prettier’s rules. This is your go-to for pretty json extension vscode a large set of files.
    • npm run check-format: This command will check if any JSON files are not formatted according to Prettier’s rules, returning an error if inconsistencies are found. This is great for CI/CD pipelines.
  • Gulp/Webpack Integration: For more complex build processes, you can use Gulp plugins (e.g., gulp-prettier) or Webpack loaders (though less common for pure JSON formatting) to run formatting tasks as part of your asset compilation or pre-commit checks.

Implementing Git Hooks with Husky or lint-staged

Git hooks allow you to execute scripts automatically at certain points in the Git workflow (e.g., before committing, after committing). This is an excellent way to enforce formatting before code ever reaches the repository, ensuring that all format json extension vscode happens locally.

  • Husky: A popular tool for easily setting up Git hooks.
    1. Install Husky: npm install --save-dev husky
    2. Add Hook: In package.json, configure Husky to run a pre-commit script. For example, to ensure all staged JSON files are formatted: 
      "husky": {
  "hooks": {
    "pre-commit": "npm run format-staged-json"
  }
},
"scripts": {
  "format-staged-json": "lint-staged"
}
  • lint-staged: Used in conjunction with Husky, lint-staged allows you to run commands only on files that have been staged for commit, making the pre-commit hook very fast.
    1. Install lint-staged: npm install --save-dev lint-staged
    2. Configure lint-staged: In package.json, add a lint-staged configuration: 
      "lint-staged": {
  "*.json": "prettier --write"
}

    Now, every time you run git commit, lint-staged will automatically prettier --write any staged .json files before the commit is finalized. If formatting occurs, the changes are automatically re-added to the commit. This provides an invisible yet highly effective mechanism for ensuring every piece of JSON adheres to your project’s styling. This automation is a significant step towards creating a robust development environment. Excel convert seconds to hms

Troubleshooting Common JSON Formatting Issues in VS Code

Even with the best tools, you might occasionally encounter issues when trying to prettify json extension vscode. Understanding common pitfalls and their solutions can save you valuable debugging time. Most problems stem from invalid JSON syntax, incorrect formatter settings, or conflicts between extensions.

Invalid JSON Syntax Errors

The most frequent reason for a formatter failing is invalid JSON. A single misplaced comma, an unclosed brace, or a missing quote can render your entire JSON invalid, preventing any formatter from processing it.

  • Error Messages: VS Code will typically highlight syntax errors with red squiggly lines and provide detailed error messages in the “Problems” panel (Ctrl + Shift + M or Cmd + Shift + M). Common errors include:
    • “Expected comma”
    • “Expected property name or ‘}’”
    • “Unterminated string”
    • “Bad control character in string literal”
  • Troubleshooting Steps:
    1. Check for Trailing Commas: JSON does not allow trailing commas after the last element in an array or object. Many developers accustomed to JavaScript might mistakenly add them.
    2. Ensure Double Quotes for Keys and String Values: All keys and string values in JSON must be enclosed in double quotes ("). Single quotes (') are not allowed.
    3. Verify Commas Between Key-Value Pairs: Ensure a comma separates each key-value pair in an object and each element in an array.
    4. Escape Special Characters: If your string values contain double quotes or backslashes, they must be escaped with a backslash (e.g., "\"quoted text\"").
    5. Use an Online Validator: If VS Code’s error messages aren’t clear, copy your JSON into an online JSON validator (like jsonlint.com or jsonformatter.org). These tools often provide more descriptive error locations. Our own online tool for prettifying JSON can also help identify and fix common issues, acting as a quick json beautifier extension vscode outside of your editor.

Formatter Not Running or Applying Incorrectly

Sometimes, the prettify json vscode shortcut might not work as expected, or the formatting applied isn’t what you configured.

  • Check Default Formatter Settings:
    • Go to File > Preferences > Settings (or Code > Preferences > Settings).
    • Search for "editor.defaultFormatter" and ensure it’s set to your desired formatter (e.g., “esbenp.prettier-vscode” for Prettier).
    • Search for "editor.formatOnSave" and enable it if you want automatic formatting on save.
    • Ensure that JSON-specific settings for indentation (json.format.insertSpaces, json.format.tabSize) are correctly configured.
  • Language Mode: Verify that VS Code’s language mode (shown in the bottom-right status bar) is set to “JSON” for the file you’re working on. If it’s plaintext or another language, the JSON formatter won’t be activated. Click on the language mode and select “JSON”.
  • Extension Conflicts: If you have multiple prettify json extension vscode extensions installed, they might conflict.
    • Disable and Re-enable: Try disabling other formatting extensions temporarily to see if the issue resolves.
    • Uninstall Redundant Extensions: It’s generally best to stick to one primary formatter (like Prettier) and uninstall others to prevent conflicts.
  • Workspace vs. User Settings: Remember that workspace settings (.vscode/settings.json) override user settings. If you’re seeing unexpected behavior, check the workspace settings first.

Large JSON Files and Performance

Very large JSON files (e.g., multiple megabytes) can sometimes cause performance issues during prettify json extension vscode operations, leading to delays or even freezes.

  • Increase VS Code Memory: For extremely large files, you might need to allocate more memory to VS Code. This is an advanced setting and should be used with caution. You can modify the max_old_space_size in the argv.json file (accessible via Code > Preferences > Configure Runtime Arguments on macOS, or similar on Windows/Linux). For example, adding "max_old_space_size": 4096 would increase memory to 4GB.
  • Process in Chunks: For incredibly massive files that regularly cause issues, consider external tools or scripts to process them in chunks rather than loading the entire file into VS Code at once. This approach is more robust for data manipulation rather than simple viewing/editing.
  • Use Stream Parsers: When dealing with JSON streams from APIs, consider using stream-based JSON parsers in your application code rather than loading the entire payload into memory before pretty json extension vscode. This is more efficient for large datasets.

By understanding these common issues and their solutions, you can effectively troubleshoot and maintain a smooth JSON formatting workflow in VS Code, maximizing your productivity and ensuring data integrity. Free online survey tool canada

Integrating External JSON Tools and Services with VS Code

While VS Code and its extensions provide excellent native capabilities, sometimes you need to interact with external json beautifier extension vscode tools or services for more specialized tasks, such as validating against complex schemas, transforming data, or simply sharing formatted JSON. Seamless integration can streamline your workflow and avoid constant context switching.

Using curl or Postman for API Responses

When working with APIs, you often receive raw JSON responses that need prettify json vscode shortcut for readability.

  • Postman/Insomnia: These dedicated API clients are excellent for making requests and automatically pretty json extension vscode the responses. You can then copy the formatted JSON directly into VS Code.
  • curl and jq: For command-line enthusiasts, curl can fetch the JSON, and jq (a lightweight and flexible command-line JSON processor) can immediately format json extension vscode it. 
    curl -s https://api.example.com/data | jq .

    The jq . command pipes the raw JSON output to jq, which then prints it prettified. You can then copy this output into VS Code. jq is incredibly powerful for filtering and transforming JSON on the command line.

Online JSON Validators and Formatters

For quick one-off formatting or validation without opening VS Code, online tools are incredibly useful. Our very own prettify json extension vscode tool here provides an immediate way to clean up JSON snippets.

  • JSONLint: A classic online validator that tells you exactly where your JSON is invalid.
  • JSON Formatter & Validator: Many online tools offer both formatting and validation, often with options for different indentation levels.
  • When to Use: These are perfect when you receive a JSON string in an email, a chat message, or a simple log and need to quickly make it readable before pasting it into your project or sharing it.

Leveraging VS Code Extensions for External Data Sources

Some VS Code extensions enhance the handling of JSON from external sources or provide deeper integration with specific services.

  • REST Client: This extension allows you to send HTTP requests directly from a .http or .rest file in VS Code. The responses are then displayed, and typically automatically pretty json extension vscode, within VS Code itself. This is an excellent alternative to Postman for quick API testing.
  • Docker/Kubernetes Extensions: When working with containerized applications, configuration files like docker-compose.yml or Kubernetes manifests (.yaml, .json) often contain JSON-like structures. These extensions provide schema validation and intelligent completion for these files, ensuring they are correctly structured.
  • Database Tools Extensions: Extensions that connect to databases (e.g., PostgreSQL, MongoDB) often allow you to query data and view results in JSON format, often with built-in formatting options, making it easy to grab and prettify json vscode shortcut query results.

Best Practices for Working with JSON in a Team Environment

Consistent JSON formatting is not just about personal preference; it’s a critical component of collaborative development. In a team setting, inconsistent formatting leads to unnecessary Git diffs, debates over style, and a general drain on productivity. Establishing clear best practices ensures that all prettify json extension vscode efforts align, fostering a smoother workflow. Reverse binary number

Standardizing Indentation and Formatting Rules

The most important step is to agree on a common set of formatting rules.

  • Use .editorconfig: This file (.editorconfig) allows you to define coding styles (like indentation, line endings, character sets) that are shared across different editors and IDEs. Most modern editors, including VS Code, have native or extension support for .editorconfig. 
    # .editorconfig
root = true

[*]
indent_style = space
indent_size = 2
charset = utf-8
end_of_line = lf
insert_final_newline = true

[*.json]
indent_size = 4  ; Override for JSON to use 4 spaces

    This file acts as a universal guide for your format json extension vscode settings, ensuring everyone’s editor behaves the same way.

  • Prettier Configuration: As discussed, Prettier is excellent for this. Its .prettierrc file lives in your project root and dictates how all prettify json extension vscode operations should occur. When Prettier is set as the default formatter and Format On Save is enabled, consistency is virtually guaranteed.
  • Documentation: Document your chosen formatting standards in your project’s README.md or a CONTRIBUTING.md file. This provides a clear reference for new team members.

Leveraging Version Control for Formatting Consistency

Git and version control systems are crucial for maintaining code quality, and this extends to JSON formatting.

  • Pre-commit Hooks: The most effective way to enforce formatting is through pre-commit Git hooks, often implemented with Husky and lint-staged. This ensures that every JSON file committed to the repository is automatically pretty json extension vscode according to the defined standards. If a file is not formatted, lint-staged will automatically fix it before the commit, or even prevent the commit if a non-fixable issue exists. This eliminates the possibility of unformatted code entering your codebase.
  • CI/CD Checks: Integrate a formatting check into your Continuous Integration (CI) pipeline. Use prettier --check (or a similar command for your chosen formatter) in your CI build. If any files are not formatted correctly, the build should fail, signaling that the developer needs to run the formatter locally. This provides a final safety net for format json extension vscode.

Educating Team Members and Onboarding

Technology alone isn’t enough; proper education and onboarding are essential for fostering a culture of consistent code quality.

  • Training Sessions: Conduct short training sessions for new team members on how to set up their VS Code environment for JSON formatting, including installing recommended extensions and configuring Format On Save.
  • Code Reviews: During code reviews, highlight formatting inconsistencies as minor issues and guide developers toward using the automated tools. Over time, this reinforces the importance of using prettify json extension vscode tools consistently.
  • Templates: Provide JSON file templates for common configurations or data structures. These templates can already be pretty json extension vscode and include $schema definitions, guiding developers to maintain the correct structure and style from the start.

By implementing these best practices, teams can significantly reduce friction caused by inconsistent formatting, allowing them to focus on delivering features and value rather than battling over cosmetic code differences. The investment in setting up these processes for prettify json extension vscode pays dividends in terms of developer happiness and project maintainability.

Exploring Alternatives for JSON Formatting Beyond VS Code

While VS Code excels at prettify json extension vscode, it’s valuable to be aware of other tools and methods for JSON formatting. Sometimes, you might be working outside of VS Code, or a specific task might be better suited for a dedicated utility. Understanding these alternatives rounds out your json beautifier extension vscode toolkit. Free online survey tool australia

Command-Line Tools for Quick Transformations

For scripting, automation, or quick one-off tasks, command-line JSON processors are incredibly powerful and efficient.

  • jq: As mentioned before, jq is the quintessential command-line JSON processor. It’s like sed or awk for JSON. To simply prettify json vscode shortcut a file: 
    cat data.json | jq . > data_prettified.json

    Or directly format a string: 

    echo '{"name":"Alice","age":30}' | jq .

    jq can also filter, transform, and extract data, making it indispensable for working with JSON in shell scripts. It’s the ultimate format json extension vscode companion for automating tasks.

  • python -m json.tool: Python’s standard library includes a simple JSON tool. If you have Python installed, you can use it to pretty-print JSON. 
    cat data.json | python -m json.tool > data_prettified.json

    This is a quick and easy way to pretty json extension vscode without needing to install extra packages.

  • node -e: For JavaScript developers, Node.js can also be used to prettify json extension vscode from the command line. 
    node -e "process.stdin.pipe(process.stdout)" < data.json

    This reads from stdin, pipes it to stdout, and uses Node’s internal JSON parsing and stringification. For more control, you could write a small script: 

    // prettify.js
const fs = require('fs');
const input = fs.readFileSync(0, 'utf8'); // Read from stdin
try {
    const parsed = JSON.parse(input);
    console.log(JSON.stringify(parsed, null, 4));
} catch (e) {
    console.error("Invalid JSON:", e.message);
    process.exit(1);
}

    Then run: cat data.json | node prettify.js

Online JSON Formatters and Validators

As discussed, online tools provide a web-based interface for prettify json extension vscode.

  • Use Cases: Ideal for quick checks, when you don’t have your development environment set up, or for sharing formatted JSON with non-technical users. They are also useful for verifying JSON from third-party APIs or logs.
  • Features: Many offer options for indentation spaces (2, 4, tabs), minification, and visual tree views of the JSON structure. Some even allow you to prettify json extension vscode and validate against JSON schemas.
  • Security Considerations: Be cautious when pasting sensitive data into online tools. For confidential information, always prefer local tools or trusted internal services.

Dedicated JSON Editors and IDEs

While VS Code is a top-tier choice, other editors and IDEs also offer strong JSON support. Free online assessment tools for recruitment

  • JetBrains IDEs (IntelliJ IDEA, WebStorm, PyCharm): These powerful IDEs have excellent built-in JSON support, including prettify json extension vscode, schema validation, and context-aware auto-completion, often surpassing VS Code’s native capabilities in terms of depth. They automatically format json extension vscode when you open a file or save.
  • Sublime Text: A lightweight text editor with a vibrant plugin ecosystem. With packages like “Pretty JSON,” it can also pretty json extension vscode effectively.
  • Atom: Another open-source editor that offers similar extensibility to VS Code, with many json beautifier extension vscode packages available.
  • Notepad++ (Windows): A simple text editor for Windows with a “JSON Viewer” plugin that can prettify json extension vscode and collapse/expand nodes.

Each of these alternatives has its strengths, and the best choice depends on your specific needs, environment, and workflow.
