Spreadsheet splitter
Split Spreadsheet by Column Online
Split a spreadsheet by column when one large file needs to become separate files for each customer, location, status, team, or category. Every unique value in the column you choose becomes its own output file.
SheetSweep keeps the original headers and file format, and collects empty group values into a clearly labeled blank file. Multi-sheet Excel workbooks let you choose the sheet before splitting.
Download individual CSV or Excel groups, or save every split file together in one ZIP. Your source spreadsheet is never modified.
Open the SplitterPrivate by design. Your files never leave this browser tab — no uploads, no servers, no signup. What happens in your spreadsheet stays in your spreadsheet.
