What this tool does

JSON Diff gives you a fast, focused way to compare two valid JSON documents by path and report added, removed, and changed values. Everything runs locally in this tab.

The result is produced only after the input is checked. If the value cannot be processed, the workspace reports a specific error instead of guessing.

Limitations

  • Review important output before using it in production.
  • Very large inputs remain subject to browser memory limits.
  • Object key order is ignored because it does not change JSON meaning.
  • Arrays are compared by numeric position; moved items may appear as multiple changes.
