Enter two JSON values and select Compare.
256 KiB per input. Arrays compare by index. Paths use JSON Pointer: ~1 means /, ~0 means ~; (root) means the whole value. JavaScript parsing can round large numbers and collapses duplicate keys.

How to use it
Paste Before and After JSON, then select Compare. Object key order and whitespace are ignored. Arrays compare by index. Errors identify the invalid side; Clear resets both inputs and the results.
