XLSXCSVXLSX to CSV Converter
CSV is what importers, databases and scripts actually want. This converter takes an XLSX workbook and writes clean CSV locally — and, unlike a lot of tools, it enumerates every sheet rather than quietly exporting the first one.
Drop in your files — A CSV per sheet, named after the sheet it came from.
Why convert
Why convert XLSX to CSV?
Nearly every system that accepts a data upload accepts CSV, and many accept nothing else. It is plain, portable and free of the formatting, formulas and macros that make a workbook awkward to consume programmatically.
- A system will only import CSV and your data is in a workbook.
- You need to feed spreadsheet data into a script or a database.
- A multi-sheet workbook has to become one file per sheet.
- You want the values without the formatting, formulas or macros.
