Frequently Asked Questions

What does formatting JSON do?

Formatting (or "beautifying") re-indents JSON with consistent spacing and line breaks so it is easy to read and debug. It does not change the data — only the whitespace.

How do I find a JSON syntax error?

Paste your JSON and click Format. If it is invalid, the validator reports the parser error message (for example a missing comma or unquoted key) so you can locate the problem.

What is JSON minification for?

Minifying removes all unnecessary whitespace to shrink the payload. Use it for API responses, config bundled into apps, or anywhere smaller transfer size matters.

Is my JSON uploaded anywhere?

No. Parsing, formatting and minifying all run locally in your browser. Nothing is sent to a server, logged or stored.
