One sheet,
too many regions in it.
Group rows by a column's value — like Region or Status — and fan them out into separate tabs in one workbook. Runs entirely in your browser; handles workbooks with thousands of rows.

What it does
- Groups rows by any column — Region, Status, Owner, whatever value you split on
- One tab per unique value — with sensible, deduplicated, Excel-safe sheet names
- Keeps the header row — repeated at the top of every tab, optional
Questions
Is my workbook uploaded anywhere?
No. The file is read and processed entirely in your browser using JavaScript. Nothing is sent to a server.
What if two group names would create the same tab name?
Sheet names are automatically deduplicated with a numeric suffix, and shortened if they exceed Excel's 31-character tab-name limit.
