One focused problem
Choose the shared columns, bring across the fields you need, and review rows that could not be matched safely.
About RowPair
Spreadsheet matching should feel like a small job, not a new skill.
RowPair is an independently operated web tool for connecting two tables by the column they share. It is built for people who need a dependable answer without maintaining formulas or uploading business data to a third-party workspace.
Private by architecture
Spreadsheet reading, matching, and exporting happen locally in your browser. RowPair does not receive your file contents.
Review before trust
Missing keys, duplicate values, and ambiguous matches are surfaced because a polished download is not useful if the join is wrong.
What RowPair is for
Routine joins between files people already use.
Common jobs include enriching customer lists, reconciling exports, updating supplier prices, and replacing a one-off XLOOKUP.
RowPair is not a database, a permanent data-cleaning pipeline, or a substitute for reviewing consequential financial or operational work.
There is no account requirement. Limited first-party usage statistics help improve the site, but they exclude spreadsheet contents, filenames, match columns, and persistent visitor identifiers.
