# JSON Diff Paste two JSON documents and see exactly what changed — every added, removed and changed key reported by its path, ignoring key order and whitespace. All compared in your browser. ### How it works Both sides are parsed with `JSON.parse` and compared key-by-key down every nested object and array. Each difference is reported by its dotted path as **added**, **removed** or **changed** (with old → new values); arrays are compared element-wise, so a new item shows as `arr.2 added` rather than a whole-array change. Because it's structural, key order and whitespace are ignored. Nothing is uploaded. --- *Source: [ocxly.com/json-diff.html](https://ocxly.com/json-diff.html) — OCXLY, free 100% client-side privacy-first tools.
