What is Excel to CSV Converter?
Excel workbooks hold several sheets, formats and formulas, while databases, scripts and import tools want plain CSV. This converter reads .xlsx, .xls, .xlsm and .ods files locally with SheetJS and writes the chosen sheet as delimited text.
When the workbook has more than one sheet, a sheet picker appears above the result. You can export raw values, where numbers are unformatted and dates become ISO 8601, or the text exactly as displayed in Excel. Formulas are exported as their last calculated values, and macros are never run.
How does it work?
- Drop an Excel, ODS or CSV file on the drop zone (up to 50 MB).
- Pick the sheet from the selector that appears for multi-sheet workbooks.
- Choose the delimiter (comma, semicolon, tab or pipe), quoting and whether to keep raw or displayed values.
- Copy the CSV or download it; the file name follows the workbook and sheet.
Common use cases
- Loading a spreadsheet into a database or a data pipeline that reads CSV.
- Exporting one sheet of a large workbook for version control or diffing.
- Producing a semicolon-separated file for a system with European settings.
- Extracting data from an old .xls file without opening Excel.

Privacy
Excel to CSV Converter runs entirely in your browser. The text or files you provide are processed on your device and are not uploaded, logged or stored on our servers.
Limitations
Only cell values are exported: styles, charts, images, merged-cell layouts and formulas are not. Password-protected workbooks cannot be opened.
Frequently asked questions
Are my files uploaded?
No. The workbook is read in your browser by a local library, so confidential spreadsheets stay on your device.
What happens to dates?
In raw mode date cells are written as ISO 8601 (2024-01-15 or 2024-01-15T13:45:00). Choose "As displayed in Excel" to keep the workbook format instead.
How do I export another sheet?
Use the sheet selector shown above the result; the CSV and the download name update immediately.
