Frequently asked questions

Is the JSON Formatter free to use?

Yes. The JSON Formatter is completely free with no sign-up, no usage limits and no watermarks. Use it as many times as you like.

Is my data safe and private?

Absolutely. The JSON Formatter processes everything inside your browser — your input is never uploaded to any server, so your data stays 100% private.

Does this run completely offline?

Yes. All processing happens in your browser using JavaScript, so once the page has loaded you can keep using it with no internet connection — and none of your code or data is ever sent to a server.

Do I need to install anything or use it on mobile?

No installation needed. The JSON Formatter works in any modern browser on desktop, tablet and mobile.

What is the difference between beautify and minify?

Beautify adds indentation and line breaks so JSON is easy to read, while minify strips all whitespace to make the file as small as possible for transfer or storage.
