What is the JSON Diff Checker?
JSON Diff Checker is a free online tool that compare two JSON documents with path-level added, removed, and changed highlights.
JSON diffs help you review API responses, config changes, and localization files without staring at raw dumps. Path-level highlights show exactly what moved.
Paste original and updated JSON to get counts of additions, removals, and value changes — all in your browser.
How to diff JSON
- Paste the original JSON on the left and the updated JSON on the right.
- Review added (green), removed (red), and changed (amber) paths.
- Fix your payload or config based on the table, then re-check.

Frequently asked questions
Does order of object keys matter?
No. Comparison is by path/value. Array indexes are compared positionally.
