A small menu-bar companion for messy spreadsheets. Rowmate cleans, merges, and dedupes CSVs right on your Mac. No uploads. No servers. No accounts Rowmate is a small menu-bar companion for messy CSV files. It cleans, merges, and dedupes spreadsheets entirely on your Mac. No uploads. No servers. No accounts. No telemetry. Your data never leaves your machine. Drop a CSV into the menu bar popover and Rowmate processes it in seconds. What you can do: • Trim whitespaces in cells and drop empty rows • Title-case names or any other data (BOB SMITH → Bob Smith) • Clean email addresses (strip mailto: prefixes, surrounding brackets, +tags) • Mask emails, phones, names for sharing or screenshots • Normalize LinkedIn URLs (strip tracking parameters, country prefixes and fix %-encoded characters) • Unify mixed date formats into one consistent style • Deduplicate rows - even when the duplicates aren't identical • Merge two files with append, inner join, left join, or "only in first" modes Built for anyone who is tired of doing the same cleanup by hand: trimming whitespace, fixing capitalization, stripping tracking parameters, deduplicating exports, merging. Rowmate handles the repetitive parts so you can focus on more meaningful work. Questions or feedback? help@oitoana.dev

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

• Excel-compatible export now also converts the file to a comma-separated .csv, so semicolon and tab files open cleanly in Excel, Numbers, and Google Sheets with no extra setup. • Email cleanup handles a few more messy formats, so dedup and masking stay accurate on awkward exports
