Frequently Asked Questions

What does a JSON formatter do?

A JSON formatter takes raw or minified JSON and adds proper indentation, line breaks, and spacing to make it readable. It also validates whether the JSON is correctly structured.

How do I validate JSON?

Paste your JSON in the input box and click Format JSON. If it's invalid, a red error message will show the exact problem.

What is JSON minification?

Minification removes all whitespace and line breaks from JSON to make it as compact as possible — useful for APIs and reducing file size.

Is the JSON formatter free?

Yes, completely free. No sign-up, no limits, works entirely in your browser.
