Frequently asked questions

How are paths reported?
Each differing leaf is shown with a dotted and bracketed path such as user.tags[2], so you can locate the exact change.
Does the order of object keys matter?
No. Objects are compared by key, so reordered keys are not reported as differences.
Is my data uploaded?
No. Both documents are compared entirely in your browser and nothing is sent to a server.
