About JSON Diff

JSON Diff highlights the exact paths that changed between two JSON documents — essential when reviewing API responses, config drift, or test snapshots. The tool walks both trees recursively, classifying every path as added, removed, or changed, and renders before/after values so reviews are fast.

Frequently asked questions

No — object keys are compared by name, not position. Array elements are compared by index.
Any path that exists in both sides but with different values. Type changes (number vs string) are flagged as changed.
No. The diff runs entirely in your browser.
