Excel to CSV
Convert Excel workbooks (XLSX/XLS) to CSV. Export one sheet or all sheets as a ZIP.
About Excel to CSV
Excel to CSV converts XLSX and XLS workbooks into plain CSV — export a single sheet on its own or every sheet at once bundled in a ZIP. It's the fast path from a spreadsheet to a format that imports cleanly into databases, scripts, and other tools. Conversion runs entirely in your browser, so the workbook is never uploaded.

Frequently asked questions
Can I convert just one sheet?
Yes. Export a single chosen sheet, or export all sheets together as a ZIP of CSV files.
Does it support old .xls files?
Yes. Both modern XLSX and legacy XLS workbooks are accepted.
What happens to formulas?
CSV stores values, not formulas, so each cell becomes its computed value.
Is my spreadsheet uploaded anywhere?
No. The conversion happens in your browser, so the workbook never leaves your device.
How are multiple sheets named in the ZIP?
When you export all sheets, each becomes its own CSV file inside the ZIP, named after the source sheet.
