How to Use
Compare two JSON payloads, review changes per path, then export the results.
1
Enter JSON A and B
Paste payloads directly or upload .json files on both panels. Use Format Both if you want a cleaner view.
2
Run JSON Compare
Click Compare JSON to see changes per path with categories added, removed, and changed.
3
Export or Share
After review is complete, use Export JSON, Download Patch, or Copy Patch for documentation and code review.
Best Practice
For large payloads, use Swap A and B if the change direction feels reversed, so the before/after narrative is easier for the team to read.
