About JSON Diff

With JSON diff, you can inspect API response changes directly in the browser.

Formatting both documents first with the JSON formatter can reduce mistakes before comparison.

FAQ

Does key order count as a difference?

JSON object key order is usually not important, but array order is meaningful and will appear as a difference.

What about large files?

Performance may decrease with deep trees; compare the data in smaller parts when necessary.

Is YAML supported?

This tool is focused on JSON, so YAML should be converted to JSON first.
