Carregando ferramenta…
Compare two versions of a JSON payload, config, or API response. Key order normalization shows only what actually changed.
How to use
- Paste the original JSON into the JSON document field (side A).
- Paste the JSON to compare into the Compare with field (side B).
- Keep Normalize key order on to ignore differences that are only about ordering.
- Choose Unified or Side-by-side view and check the summary of added, removed, and unchanged lines.
Good to know
- Both sides are formatted the same way before comparing, so whitespace and line breaks do not count as changes.
- The document stays available in the other JSON tools (format, query, validate…) in this browser tab.
- The comparison runs in your browser.
