01
Paste data or read from a file.
02
Review the options; results update automatically. Run manually for larger inputs, and check warnings before applying changes.
03
Copy or download the result. Your original document stays unchanged until you apply it.

Object key order is ignored. Array order and value types are significant.

Frequently asked questions

Can I recover my documents after closing the page?

Documents are saved automatically in this browser and restored when you return. Closing a document with X deletes it. Browser cleanup can also remove saved work; download important results or export your workspace.

Does key order affect the comparison?

Object key order is ignored. Array order, value types and changed paths still affect the result.
