info About this tool
Easily convert your Excel spreadsheets to CSV format with our free online tool. This converter extracts data from the first sheet of your workbook and saves it as a standard Comma Separated Values file, compatible with any data application. No complicated software needed.

File size: CSV output is typically 80–90% smaller than the original XLSX file, since CSV stores only raw values with no formatting metadata.

Quality: Only data values are exported: formulas, charts, images, conditional formatting, and cell styles are not preserved in CSV.
