Question 1

How does JSON structural comparison work?

Accepted Answer

JSON structural comparison recursively traverses both objects, comparing keys and values at each level. It detects four types of differences: added (key exists only in right), removed (key exists only in left), changed (same key, different value or type), and unchanged. Array elements are compared by index.

Question 2

Can this tool compare nested JSON?

Accepted Answer

Yes. The tool recursively compares nested objects and arrays to any depth. Each difference shows its full path (e.g., user.profile.email or items[2].name) so you can locate changes precisely.

Question 3

What happens when JSON types change?

Accepted Answer

Type changes (e.g., number 42 changed to string "42", or object changed to array) are detected as "changed" differences. The tool shows both the old and new values with their types.
