Can this validate invalid JSON?

Yes. Invalid JSON shows an error message with the parse failure reason.

Does formatting change my data?

Formatting only changes whitespace and indentation. Values remain identical.

Paste JSON to format with indentation, minify, or validate syntax. Errors show the parse message. Processing is local — nothing is uploaded.

Pretty-print or minify JSON and surface parse errors. Processing stays in your browser.
