Frequently Asked Questions

What is a JSON formatter?

A JSON formatter is a tool that takes raw or minified JSON data and reformats it with proper indentation and line breaks, making it easy to read and debug. It can also validate whether your JSON is syntactically correct.

How do I validate JSON online?

Paste your JSON into the input field and click "Validate". The tool will parse your JSON and tell you whether it is valid or show you the exact error message if it is not.

What is the difference between JSON beautify and minify?

Beautify (or pretty-print) adds indentation and line breaks to make JSON human-readable. Minify removes all unnecessary whitespace to reduce file size, which is useful for production environments.

Is my data safe when using this JSON formatter?

Yes. This tool runs entirely in your browser. No data is sent to any server. Your JSON never leaves your computer.
