What does JSON Diff actually do?

JSON Diff compares two parsed JSON values and reports added, removed, and changed paths. It is a structural diff, not a text diff. Key order does not matter. It does not merge the two documents.

When should I use JSON Diff?

Use it when two API payloads should match and a text diff is too noisy.

When should I not use JSON Diff?

Do not use it to compare YAML or plain logs.

What does JSON Diff not do?

Both sides must parse as JSON. Does not produce a JSON Patch you can apply blindly without reading it.
