What is this tool?

Converts data between Excel (.xlsx) and CSV formats, useful for moving data between spreadsheet software and systems that expect the simpler CSV format.

How to use it

Upload your file, and it converts automatically between formats. Download the converted result.

CSV files don't preserve formatting, formulas, or multiple sheets — if your Excel file relies on those, expect to lose them in the conversion, since CSV is deliberately a plain, structure-only format. If your Excel file has more than one sheet, only the first sheet is converted (that's what "CSV" itself supports -- one flat table, not a workbook).
