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.

  • Get an Excel report into a shape a Python or pandas script can read directly
  • Convert a legacy .xls file to CSV for a tool that won't open the old binary format
  • Strip Excel formatting and formulas down to raw comma-separated values
  • Prepare spreadsheet data for a bulk upload that requires CSV input

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.
