FAQ

How does the JSON diff work?

The tool performs a deep comparison of both JSON structures, comparing every key and value recursively. It detects additions (keys in modified but not original), removals (keys in original but not modified), and changes (same key, different value).

Does order matter when comparing?

For objects, key order does not matter — only the values are compared. For arrays, order matters — elements are compared by index position.
