JSON Formatter
Paste JSON to pretty-print it with your preferred indentation, minify it to a single line, or just validate it — syntax errors are reported with their exact position so you can fix them fast. Everything runs locally; API responses you paste stay private.

Frequently asked questions
Is pasted JSON sent anywhere?
No — formatting uses your browser's native JSON parser. Sensitive payloads never leave the page.
What's the difference between beautify and minify?
Beautify adds indentation and line breaks for reading; minify strips all insignificant whitespace for the smallest possible payload. Both produce semantically identical JSON.
