What this tool does

The JSON Difference Viewer compares two JSON documents and highlights added, removed, changed, and unchanged fields with clear paths and values.

How to use it

  1. Paste your original JSON on the Source tab and the updated JSON on the New tab.
  2. Use the Results tab to see path-by-path differences with old and new values.
  3. Toggle “Show unchanged paths” if you want full context; leave it off for a concise diff.

Tips

  • Click “Format” on each input to pretty-print and reduce parse errors.
  • For large payloads, keep unchanged items hidden to focus on changes.
  • All diffing runs locally in your browser; no data is sent to a server.
