How to use
Paste raw JSON, format or minify it, then copy the output or inspect the line and column hint if parsing fails.
Examples: prettify API payloads, debug webhook bodies, or compress config JSON before sharing it in chat or docs.
FAQ: This formatter validates JSON structure in the browser. It does not auto-repair malformed JSON, but it does surface the parse location and a short repair hint.
