What is a JSON Formatter?

JSON (JavaScript Object Notation) is a lightweight data-interchange format used heavily in APIs and configuration files. Raw JSON from an API is often minified (no whitespace) making it very hard to read.

Our JSON Formatter takes your raw or minified JSON and instantly reformats it with proper indentation, line breaks, and structure — making it easy to read, debug, and share.

How to Use

  1. Paste your JSON into the input box above.
  2. Choose your preferred indentation size (2 or 4 spaces).
  3. Click Format JSON.
  4. View the cleaned output, then copy or download it.

JSON Formatter FAQ

Does this work with large JSON files? +
Yes, our formatter handles large JSON payloads. For very large files (over 5MB), consider using a local tool like VS Code or jq for best performance.
Is my JSON data sent to your servers? +
Formatting is handled server-side via our API, but your JSON is never stored, logged, or retained in any way. It's processed and returned immediately.
Can this validate my JSON? +
Yes. If your JSON has syntax errors, the formatter will display a clear error message showing what went wrong and where, making it easy to fix issues.
