How it works
How it works
- Parses rows by splitting on commas (no quoted fields). Each row is keyed by joining cells with a rarely used separator (U+0001).
- Diff: computes only in A and only in B by set difference of row keys.
- Merge: performs a union by last‑write‑wins over the composite row key.
- Limitations: no support for quoted commas, escapes, multiline fields, or type inference—targets simple CSV.
Privacy & Security
No upload; local only.
Accuracy, Limits & Tips
