One column,
too many things in it.
Split one xlsx column into several — by delimiter or fixed width — right in your browser. Nothing is uploaded anywhere; handles workbooks with thousands of rows.
1. Choose a workbook
Drop an .xlsx file here, or click to browse
.xlsx / .xls — processed entirely on your device
What it does
- Delimiter splits — break a column on commas, tabs, spaces, pipes, or a custom string or regex
- Fixed-width splits — break a column at specific character positions instead
- Keeps or drops the original column — your choice, with a live preview before download
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 happens to rows where the split produces fewer parts than others?
Shorter results are padded with empty cells so every row lines up under the same set of new columns.
