Frequently Asked Questions

How does the JSON Diff tool work?

Both JSON inputs are parsed, normalised, and pretty-printed with the same indentation, then compared line by line. Lines that differ are highlighted — red on the left, green on the right.

Does key order affect the diff?

Yes. Both JSONs are compared after normalisation (pretty-printing), so different key ordering will show as differences. If you want order-independent comparison, sort both JSONs first.

Does it handle deeply nested JSON?

Yes. Both objects are fully parsed before comparison, so the diff works regardless of nesting depth.
