Convert Excel Worksheets to CSV
Choose an .xlsx file and this tool shows each worksheet as CSV, ready to import into a database, a CRM, an online shop or a script. Pick the worksheet and the delimiter — comma, semicolon, tab or pipe — and copy the text or download a .csv file.
Cell values are exported as they are stored: text, numbers, and the results of formulas; dates come out in the unambiguous ISO format (YYYY-MM-DD). The downloaded file is UTF-8 with a byte order mark, so Excel opens it again with all characters intact. Everything happens in your browser.
Why Use This Excel to CSV Converter?
- Every worksheet of the workbook available
- Comma, semicolon, tab or pipe as delimiter
- Dates in ISO format, formulas as their values
- Read in your browser — nothing is uploaded

Frequently Asked Questions
Is this Excel to CSV converter free?
Yes, it is completely free and has no limits.
My workbook has several sheets — which one is converted?
You choose. The list shows every worksheet with its number of rows; the CSV is created for the selected one, and the file name includes the sheet name.
Are old .xls files supported?
The tool reads the modern .xlsx format used by Excel 2007 and later, Google Sheets and LibreOffice. Save an old .xls file as .xlsx first.
Is my file uploaded anywhere?
No. The workbook is read entirely in your browser; it never leaves your device.
