By default, key order is ignored so that semantically identical JSON objects are treated as equal regardless of property ordering. You can enable strict ordering mode when key sequence matters, such as when comparing serialized output or verifying specific JSON generation logic.
Yes, the tool performs deep recursive comparison of nested objects and arrays at every level. It identifies additions, deletions, and modifications within deeply nested structures and displays the full path to each change. This makes it easy to pinpoint exactly where two complex JSON documents differ.
The diff view uses intuitive color coding: green highlights for additions (new keys or values), red for deletions (removed keys or values), and yellow for modifications (changed values). This visual approach makes it instantly clear what changed between two JSON documents without reading line by line.
