An Excel file can hold up to 1,048,576 rows per sheet, but that ceiling doesn't mean a file that size is easy to work with. Large workbooks take longer to open, slow down formulas and filtering, and can be awkward to share by email or upload to systems with their own file size limits.

Can this split Excel files with multiple sheets?
Yes, you can choose which sheet to split, and the app processes it into multiple standalone files.
Do I need Excel installed to use this tool?
No, Turbo Large Data Splitter reads and writes Excel files directly, so Microsoft Excel doesn't need to be installed on your machine.
Will formulas in my Excel file be preserved after splitting?
The split files contain the underlying values from the source data; complex formulas that reference other sheets should be checked afterward, since each split file is a standalone workbook.
