About this JSON formatter
Paste any JSON document to validate it and pretty-print it with your preferred indentation, or minify it for transport. Parsing uses your browser's native JSON.parse, so the validation behavior matches what your JavaScript runtime will accept.
Everything runs locally: API responses, config files, and payloads containing secrets never leave this tab.
