Why Convert XLS to XLSX?

The .xls format, used until Excel 2003, is outdated and has limitations on rows and columns. Converting to .xlsx uses the modern XML-based format, which results in smaller file sizes, better data recovery, and support for over a million rows.

Upgrading to the XLSX format ensures your spreadsheet files remain fully compatible with Microsoft 365, Office 365, Google Sheets, and other modern data analysis tools and spreadsheet applications, while also benefiting from improved security features and significantly better data recovery capabilities.

  2. The tool converts the structure to modern XML .xlsx.
  3. Click 'Convert' to finish.
  4. Download your upgraded Excel file.
