About JSON Formatter
Beautify messy JSON, change indentation, or minify JSON for production use. The formatter is useful before code review, API debugging, log inspection, and configuration cleanup.
Common Uses
- Pretty-print minified API responses.
- Minify JSON before embedding it in an app or config.
- Standardize indentation for code review.
- Clean pasted JSON before validation or comparison.
FAQ
Can I minify JSON too?
Yes. Use the minify option to remove whitespace and line breaks from valid JSON.
What indentation sizes are supported?
You can choose compact output or common indentation styles such as two or four spaces.
Does the formatter fix invalid JSON automatically?
No. It formats valid JSON. If parsing fails, use JSON Validator to find the exact syntax problem.
Is this safe for private JSON?
The formatting runs in your browser, so the JSON is not uploaded to MKDiff.
