Questions answered
We explain meaningful limitations before conversion so you can decide whether this tool is appropriate for your document.
What happens to formulas?
The converter exports the displayed cell text available to the workbook reader. Formatting and formula definitions are not preserved in CSV.
Why do I get a ZIP?
CSV supports one table per file. Workbooks with multiple worksheets therefore produce one CSV per worksheet.
