How to use JSON Formatter

Paste your JSON, choose 2, 4, or tab indentation, and the tool formats it with syntax highlighting and line numbers.

Frequently asked questions

What indentation should I use?

2 or 4 spaces is standard. Tab indentation is preferred by some style guides like Google's.

Does it validate while formatting?

Can I format minified JSON?

Yes — paste minified JSON and it will be expanded and formatted instantly.
