JSON Diff help

See exactly what changed between two JSON documents, with the full path to each difference.

Steps

1. Paste the original JSON in A and the new one in B.
2. Every difference is listed: + added, - removed, ~ changed, with a path like user.addr.city or items[2].
3. The summary line counts each kind. Copy the diff if you need it.

How it compares

Objects are compared key by key; arrays are compared by index. A value whose type changes (object to array, number to null, and so on) is reported as one change rather than a deep diff.

Notes

• Both sides must be valid JSON; a parse error points at which side and why.
• Nothing is uploaded.

Everything runs in your browser. Nothing you enter or drop is uploaded.
