Row-level diffs for CSV exports from sheets, CRMs, and databases.
Compare two CSV files by a primary key, show added, removed, and changed rows, and export a clean report.
The desktop installer for Windows and macOS lives on the setup page. One link — then follow the steps.
Excel compare is noisy on large dumps. You need added / removed / changed by id, not a wall of red cells.
This CLI joins on a key column and writes a markdown or CSV report you can attach to a ticket.
- Join on one or more key columns
- Ignore column order and optional whitespace
- Export added, removed, and field-level changes
- Works on files larger than Excel likes to open
- Windows 10 or 11
- Python 3.11, csv, argparse, optional pandas
