About JSON Diff
Compare two JSON documents, API responses, package files, or configuration payloads. MKDiff formats JSON before comparison so nested changes are easier to inspect.
Common Uses
- Compare API responses between staging and production.
- Review changed package, lock, or configuration files.
- Find modified keys in JSON exports.
- Debug webhook payload changes.
FAQ
Does JSON Diff format JSON before comparing?
Yes. Valid JSON is formatted before comparison, which makes structural differences easier to read.
What happens if my JSON is invalid?
The tool reports a JSON format error. Use JSON Validator to locate syntax errors before comparing.
Can I compare API responses?
Yes. Paste the two responses into the panels and run the comparison locally in your browser.
Is the JSON stored?
No. The comparison happens client-side and MKDiff does not store the JSON you paste.
