Excel Open XML Workbook (XLSX) is the default spreadsheet format of Microsoft Excel since the 2007 release. An XLSX file is a ZIP package of Office Open XML parts describing worksheets, formulas, charts, and formatting. Compared with the old XLS format it is substantially smaller, supports over a million rows per sheet, and cannot contain macros — a deliberate safety measure.
How to open an XLSX file?
Microsoft Excel opens XLSX natively, and Excel for the web opens it in a browser with a Microsoft account.
Google Sheets, LibreOffice Calc, and Apple Numbers all preserve formulas and most formatting. Very complex workbooks with pivot tables or advanced charts are safest in Excel itself. To share data without letting recipients change it, convert the workbook with our XLSX to PDF tool.

Excel 97-2003 Workbook (XLS) is the original binary spreadsheet format of Microsoft Excel, built on the Binary Interchange File Format and used as the default until Excel 2007. An XLS stores worksheets, formulas, charts, and formatting in one proprietary file, and it can also carry VBA macros. Its main limitations are a ceiling of 65,536 rows per sheet and a greater risk of file corruption than the newer XLSX.
How to open an XLS file?
Current versions of Excel still open XLS in Compatibility Mode and offer to upgrade the file to XLSX.
LibreOffice Calc, Google Sheets, and Apple Numbers all read XLS. Because XLS files can contain macros, treat unexpected attachments with caution. Converting your archive keeps it safe and compact — our XLS to XLSX and XLS to PDF tools handle the job.
