How to compare Excel spreadsheets
Upload your original and revised workbook. Rows are matched by content, so a reordered row is recognized instead of showing as a delete-and-insert pair.
Switch to the Text view to see the same comparison as a classic line-by-line diff instead of a grid.
Works with full workbooks, not just a single sheet — upload .xlsx, .xls, .xlsm, .ods or .csv and compare pricing sheets, inventory exports, or financial models without installing Excel.
Which formats are supported? — .xlsx, .xls, .xlsm, .ods, and .csv.
Are formulas compared, or values? — Calculated values — the same thing you see in the cell.
Is my spreadsheet uploaded anywhere? — No — comparison runs entirely in your browser; files never leave your device unless you choose to save a comparison online.
