Frequently Asked Questions

How does JSON diff work?

JSON diff compares two JSON objects semantically — it understands the data structure, not just text. It shows you exactly which keys were added, removed or changed, even in deeply nested objects.

Can I compare JSON arrays?

Yes. The tool compares arrays element by element and highlights any differences in values or order.
