Frequently Asked Questions

Is my text data private when using this diff tool?

Yes. The diff comparison runs entirely inside your browser's memory. No text or code is ever sent to any external server.

How can I compare two messy JSON objects effectively?

First paste each JSON object into our JSON Formatter and click Sort Keys (A–Z), then paste both formatted outputs here to compare actual value changes without key-order noise.
