The Format JSON tool automatically beautifies raw JSON data, transforming it into a clean, indented structure that’s easier to read and debug.

Why it matters

Unformatted JSON is hard to scan, especially with nested objects. Formatting improves readability and makes errors easier to catch.

Advantages

• Readability: Indented JSON is easier to navigate.
• Debugging: Quickly spot missing commas or brackets.
• Collaboration: Share cleaner data with teammates.
• Word Wrap: For improved readability of long Format JSON, toggle word wrap using Alt+Z (Windows/Linux) or Cmd+Alt+Z (Mac).

Use case

When working with an API response that comes as a single line, paste it in and instantly format it for inspection.

The Minify JSON tool compresses JSON data by stripping whitespace, line breaks, and comments.

Why it matters

Minified JSON reduces file size, which improves transfer speed and saves bandwidth.

Advantages

• Performance: Faster API responses with smaller payloads.
• Efficiency: Less bandwidth usage in client-server communication.
• Storage: Reduced disk space usage for large datasets.
• Word Wrap: For improved readability of long Minify JSON, toggle word wrap using Alt+Z (Windows/Linux) or Cmd+Alt+Z (Mac).

Use case

Before deploying config files in production, minify them to optimize size without losing data.

The Escape JSON tool converts JSON data into an escaped string format, making it safe to embed within code or configuration files.

Why it matters

When embedding JSON in JavaScript, TypeScript, or other code, special characters like quotes need to be escaped to avoid syntax errors.

Reserved Characters

The following characters are reserved in JSON and are properly escaped:

• Backspace → \b
• Form feed → \f
• Newline → \n
• Carriage return → \r
• Tab → \t
• Double quote → \"
• Backslash → \\

Advantages

• Code Safety: Prevents syntax errors when embedding JSON in strings.
• Automation: Instantly escapes all special characters without manual work.
• Compatibility: Works with any programming language that uses string literals.

Use case

When you need to include JSON configuration in a JavaScript variable or pass JSON as a string parameter to an API.

Example

Input: {"name": "John", "age": 30}

Output: "{\"name\":\"John\",\"age\":30}"

The Unescape JSON tool converts escaped JSON strings back to their original, readable JSON format.

Why it matters

When receiving escaped JSON from APIs or code, you need to unescape it to view and edit the actual data structure.

Advantages

• Readability: Converts escaped strings back to formatted JSON.
• Validation: Ensures the escaped string is valid JSON.
• Editing: Makes it easy to modify JSON that was previously escaped.

Use case

When debugging API responses that return JSON as escaped strings, or when working with configuration files that store JSON in escaped format.

Example

Input: "{\"name\":\"John\",\"age\":30}"

Output: {"name": "John", "age": 30}

With Download JSON, you can save your formatted or minified JSON data as a .json file directly to your computer.

Why it matters

Downloading ensures your work is safe, portable, and ready to integrate into other projects.

Advantages

• Offline use and storage.
• Easy sharing between teams.
• Direct integration with other apps or services.

Use case

Export API responses you’ve cleaned up for testing or archiving.

The Simple Search feature lets you quickly locate keys or values inside your JSON structure.

Advantages

• Find nested keys instantly.
• Filter large JSON datasets without manual scanning.

Use case

Search for “userId” in an API response with hundreds of fields.

Advanced Search uses regular expressions (regex) for more powerful queries inside JSON.

Use case

Search for email addresses, IDs, or custom patterns across large JSON files.

Copy your JSON data with a single click using Copy to Clipboard.

Advantages

• Quickly reuse JSON elsewhere.
• Boost productivity by avoiding manual copy-paste errors.

Paste from Clipboard allows direct insertion of JSON into the editor.

Why it matters

No need to upload files—just paste and start validating immediately.

Undo Changes lets you revert previous edits with a multi-step undo history.

Use case

Fix accidental deletions without reloading your JSON.

With Redo Changes, re-apply actions that you previously undid.

This ensures smooth navigation while editing JSON.

Tree View provides a hierarchical visualization of JSON data.

Advantages

• Understand nested structures at a glance.
• Expand/collapse sections for focused viewing.

Table View transforms JSON arrays into an easy-to-read tabular format.

Use case

Compare multiple JSON objects side by side like a spreadsheet.
