How to convert Excel to CSV
Choose a workbook and download. One sheet becomes a CSV; multiple sheets become separate UTF-8 CSV files in a ZIP. You can still select one sheet to export it alone.
What changes in a CSV export?
Each CSV contains one sheet's values as plain text. Formulas, formatting, and charts are not retained. Check dates and long numbers before importing the files elsewhere.
