JSON Formatter
Beautify and format JSON with proper indentation.
Frequently Asked Questions
What does the JSON Formatter do?
It parses your JSON and re-serializes it with consistent indentation, making it easy to read and debug.
Does it validate my JSON too?
Yes — if your JSON has a syntax error, the formatter will show the exact error message instead of formatting.
Can I choose the indentation size?
Yes — you can choose between 2 or 4 spaces. The default is 2 spaces.
Is there a size limit?
There is no server-side size limit since all processing happens in your browser. Very large files (10 MB+) may be slow depending on your device.
