What this tool does

Split a large worksheet into smaller XLSX files by row count and download every part together in one ZIP archive.

The selected worksheet is divided into sequential chunks, optional headers are applied, and each chunk becomes a separate XLSX file inside a ZIP.

Only the selected sheet is split. Advanced formatting, charts, macros, and workbook-level objects are not guaranteed in the generated parts.

  • Sort the source first if the sequence of records matters.

FAQ

Does each split Excel file include the header row?

Choose Repeat header to place the first row in every part, or use the other header options.

Is the row limit applied to data rows or all rows?

With header repetition, the limit applies to data rows and the header is added separately.

Can I split every worksheet at once?

This version splits one selected worksheet per run so the resulting parts remain predictable.

What is inside the downloaded ZIP?

It contains sequentially numbered XLSX workbooks, one for each row chunk.

Will charts and macros be copied into each part?

No guarantee. The parts are newly generated data workbooks.
