Frequently Asked Questions

What is a JSON Formatter?

A JSON formatter takes raw or minified JSON text and displays it with proper indentation and line breaks, making it easy to read and debug.

Is my data safe?

Yes — ByteKit processes everything in your browser. Your JSON data never gets sent to any server.

Can I validate JSON too?

Yes! ByteKit will show an error if your JSON is invalid and highlight exactly what's wrong.
