How to use the JSON diff
-
Paste the original JSON on the left and the new JSON on the right.
-
Read the added, removed and changed values with their paths.
-
Choose whether the order of array items matters.
Frequently asked questions
Does the order of keys matter?
No. Objects are compared key by key, so the same keys in another order count as equal.
How are arrays compared?
Item by item, by position. Turn on "Ignore the order of array items" to treat arrays as sets of values.
