Frequently Asked Questions

Is my JSON data sent to any server when I use this JSON formatter?

No. The JSON Formatter runs entirely in your browser. Your JSON never leaves your device and is not stored or sent to any server.

Can I validate JSON as well as format or minify it?

Yes. Use the Validate button to check if your JSON is valid. Any syntax errors will be highlighted so you can fix them quickly.

Will this JSON formatter change the data structure?

Formatting and minifying only change whitespace and indentation. The actual keys and values in your JSON stay exactly the same.
