Split Excel Workbooks in Seconds

Excel files slow down as they grow. Formulas recalculate endlessly, filters lag, and sharing becomes difficult. Splitting a large workbook into smaller files solves all of these problems.

Upload your XLS or XLSX file, choose your row limit, and download perfectly split workbooks. Each output file includes the header row from your original spreadsheet.

Processing happens entirely in your browser. Your financial data, HR records, and customer lists stay on your device.
