Compare two JSON documents and see additions, removals, and changes.
JSON Diff compares two JSON objects or arrays field by field and highlights exactly what changed — additions in green, removals in red, and modified values shown side by side.
It's built for the everyday task of comparing API responses, config files, or test fixtures before and after a change, without needing to eyeball two blocks of text.
Array items are compared by index, so reordering a list will show as changes at each shifted index rather than a single move.
