How to use JSON Diff

Find semantic differences between two JSON documents. This JSON comparison ignores object key order and formatting, then lists the values added, removed or changed.

Paste the original JSON on the left and the updated JSON on the right.
Run the comparison to produce structured changes.
Use each JSON Pointer path to locate a changed field, then copy or download the report.

JSON Diff · Example

Input

{"name":"LocalKit","version":1}

Output

  "equal": false,
  "changes": [
    {
      "path": "/version",
      "kind": "changed",
      "before": 1,
      "after": 2
    }
  ]
}

Usage notes

Array elements are compared by index; this tool does not infer moves or match items by id.

Paths escape / as ~1 and ~ as ~0. An empty path refers to the complete root value.

Limit: 100,000 combined characters, 64 levels and 2,000 changes. Quote integers outside JavaScript safe precision.
