Frequently Asked Questions.

Everything you need to know about using this JSON tool safely and efficiently.

How does the JSON diff algorithm compare files?
The comparator performs a deep recursive structural comparison across both JSON documents, categorizing discrepancies into Added, Removed, and Modified fields regardless of key order.
Can I swap Left and Right JSON documents?
Yes. Use the Swap button inside the Diff toolbar to quickly reverse the comparison direction.
