FAQ
Does key order matter in JSON?
In JSON objects, key order is not significant, but many diffs still show changes when order differs. Use formatting and sorting options if available in the UI.
Can I diff large files?
Yes, but extremely large inputs may be slower depending on your device. Prefer pasting only the relevant parts when possible.
