About this tool
Compare JSON values and types independently of object key order, with precise paths for added, removed and changed data.
How to use
Paste or open the original and updated JSON. The table lists each changed path and both values. Reordering object properties does not count as a change; moving array items does.
Numbers retain their precision, while equivalent forms such as 1 and 1.0 compare equal. Duplicate keys are rejected. The table shows 300 changes; the JSON download includes all changes with values stored as their original JSON text. Each input supports 2 MiB, 30,000 values and 80 levels.
