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.
Sorted keys make it easier to diff two JSON files and to find specific fields quickly.
Yes — keys are sorted recursively through every level of the object.
No — only object keys are sorted. Array order is preserved.
