Question 1

How does JSON diff comparison work?

Accepted Answer

The tool parses both JSON inputs, then performs a deep recursive comparison of every key and value. Additions (keys in the right but not the left), deletions (keys in the left but not right), and modifications (same key, different value) are all highlighted with distinct colors.

Question 2

Can it handle nested JSON objects?

Accepted Answer

Yes. The diff algorithm works recursively through all nesting levels. Nested objects and arrays are compared element by element, so you can see exactly where deeply nested values differ.

Question 3

What happens with large JSON files?

Accepted Answer

Since all processing happens in your browser, there are no upload limits. However, very large files (over 5MB) may cause the diff to take a moment. The tool handles arrays, deeply nested structures, and thousands of keys without issues.

Question 4

Can I use this for API response debugging?

Accepted Answer

Absolutely. Paste the expected response on the left and the actual response on the right. The diff view instantly shows missing fields, wrong values, and extra data, making it perfect for debugging REST API responses.
