What is a JSON formatter?

A JSON formatter takes compact or unformatted JSON and adds indentation and line breaks to make it human-readable. It also validates that the JSON is syntactically correct.

Is the JSON formatter free?

Yes, completely free. No account, no limits, no file upload required.

Is my JSON data safe?

Yes. All formatting happens in your browser. Your data is never sent to any server.

Can it minify JSON too?

Yes. Switch to Minify mode to remove all whitespace and produce compact JSON for production use or API payloads.
