Frequently Asked Questions

Is my code sent to a server?

No. All formatting happens in your browser. Your code never leaves your device.

What happens if my JSON is invalid?

The formatter will show an error with the line/column of the syntax error so you can fix it.

Can I format minified code?

Yes! That's the primary use case — paste minified JSON/JS/CSS and get readable formatted output.

Does it support TypeScript/JSX?

Yes, TypeScript and JSX/TSX are fully supported.

Is there a file size limit?

No practical limit. Works with any file your browser memory can handle.
