FORMAT
Tips
Paste JSON in the left pane. Output updates instantly.
JSON processing runs entirely in your browser using the native JSON.parse and JSON.stringify APIs. Output updates instantly as you type — no server round-trip needed.
All processing happens inside your browser tab. The JSON you paste or type is never sent to a server — it stays entirely on your device.
Minified JSON is smaller, which reduces payload size in APIs, config files, and localStorage.
No — only whitespace is removed. The values, keys, and structure are unchanged.
Yes. Minified JSON is valid and parseable by any JSON parser.
