Frequently asked questions
- Does key order affect the comparison?
- By default the diff is structural: it compares values by key path, so reordering keys does not create false differences. A text mode is also available when you want a literal line-by-line view.
- What changes does it report?
- It classifies every difference as added, removed, or changed, and shows the exact key path so you can locate the divergence quickly instead of scanning two blobs by eye.
- Can I compare large documents?
- Yes. Comparison runs in your browser, so there is no upload limit. Very large files use more memory but remain private.
- Is my data uploaded?
- No. Both documents stay on your device; only the computed diff is rendered locally.
