JSON Formatter

Format, validate & minify JSON.

Runs entirely in your browser — nothing you enter is uploaded, logged, or tracked.

Paste JSON to pretty-print or minify it, with validation that points to the exact line and column of any syntax error.

Frequently asked questions

Does it validate JSON?

Yes — invalid JSON is reported with the parser’s message and the position of the error, so you can fix malformed data quickly.

Is my data safe to paste here?

Yes. Parsing and formatting happen entirely in your browser using the native JSON engine — nothing you paste leaves the page, so it is safe for private payloads.
