Frequently Asked Questions

What does JSON Diff compare?

It performs a deep structural comparison of two JSON documents, identifying added, removed, and changed keys and values at every nesting level.

Can it compare arrays?

Yes. Arrays are compared element by element by index. If one array is longer, the extra elements are reported as added or removed.

Does it handle nested objects?
