Split Excel Files Online
Separate a workbook by worksheet, fixed-size row batches, or values in a chosen column. Your file stays on your device.
Add one XLSX or XLS file up to 10 MB. The file is processed only in this browser.
Split options
Each selected worksheet becomes one XLSX. Formulas are preserved, but references to other worksheets may no longer work.
Flexible Excel splitting without uploads
Choose an explicit rule, review the output count, and download new files without changing the source workbook.
Three split modes
Export selected worksheets, create fixed-size row batches, or group rows by a column value.
Clear output report
Multi-file results include a CSV report with generated filenames, source sheets, groups, and row counts.
Local and private
Reading, splitting, previewing, and packaging happen entirely in your browser.

Excel splitter — FAQ
Is my Excel file uploaded?
No. The workbook is read, split, and packaged locally in your browser.
How many files can one split create?
The first version creates up to 200 files per task. Choose a larger row batch or another grouping column if the result would exceed that limit.
What happens to formulas?
Worksheet splitting preserves formulas, but cross-sheet references may no longer work. Row and column splitting save formula cells as their last stored values and block formulas without a stored result.
Are all Excel features preserved?
Basic values, types, number formats, widths, and supported styles are retained where possible. Macros, charts, images, pivot tables, and other advanced objects are not guaranteed.
