Everything you need to stop copy-pasting between sheets.

UnifySheets is built for ops, finance and office teams who waste hours every week reconciling spreadsheets by hand.

Auto-map with AI

Claude reads your column names and the first 3 rows, then proposes a clean mapping you can tweak in one click.

Works across languages

"Revenue", "Umsatz", "Выручка", "Venituri" — UnifySheets recognizes them as the same column.

Stack or join

Stack files vertically by matching columns, or join them horizontally on shared keys like Month + Company.

Google Sheets sync

Save the result straight to Google Drive and refresh it anytime from the same source files.

Privacy-first

All file processing happens in your browser. We only store the mapping config — never your data.

Saved mappings

Run the same merge next month with one click. Your mapping config is reusable across files.

Three steps. No formulas. No macros.

Designed for non-technical teams. The whole flow takes under a minute.
