Need a XLS version of a XLSX file? Add the source, review any available settings and convert it without installing software or creating an account.
Upload the XLSX file you want to convert. Where batch upload is available, you can add several files together.
XLS is already selected for this page. Adjust the available format or editing options only if you need them.
Start the conversion, then download and check the new XLS file.
XLSX and XLS organize content differently. Common text, tables and media are carried across, while advanced layouts, formulas, animations or embedded features may need review.
XLSX is the modern Microsoft Excel workbook format. It stores editable cells, formulas, styles, charts and multiple worksheets in a structured Open XML package.
XLSX opens in Microsoft Excel, Google Sheets, LibreOffice Calc, Apple Numbers and most modern spreadsheet editors.
XLS is the older binary Excel workbook format used by Excel 97–2003. It keeps editable cells, formulas and sheets but has lower row limits and fewer modern features than XLSX.
XLS opens in Microsoft Excel and LibreOffice Calc; convert it to XLSX for current spreadsheet features and wider compatibility.
