Structural comparison

Compare parsed data instead of raw text, so whitespace and object key order do not create false differences.

Precise JSON paths

Every change includes its exact object or array path, making large payloads easier to debug.

Private by design

Both documents stay on your device. Comparing, filtering, and exporting happen locally.

How to compare JSON

  1. 1. Add both documents. Paste JSON into each editor or open local .json files.
  2. 2. Review the changes. Filter additions, removals, and modifications or search by path.
  3. 3. Export the result. Copy a path or download a machine-readable JSON difference report.
