How to use this tool
Paste or type your input, adjust the options, then copy or download the result.
JSON, YAML and XML structured diff
Line-based diffs fail on JSON that only changed key order. A structured diff flattens both documents and reports added, removed and changed paths.
Paste two payloads in JSON, YAML or XML. The tool normalizes them and lists field-level differences so a PR review does not depend on pretty-print order.
Arrays are compared by index. Reordered lists look like many changes; for sets, sort in your app first.
