What is an .XLS file?

XLS files are spreadsheets created by Microsoft Excel or other spreadsheet applications. The files store data in worksheets and may include charts, graphs, and mathematical functions for various spreadsheets, such as quarterly financial reports, family spending budgets, or contact lists.

Excel users commonly saved spreadsheets as XLS files in the 1990s and 2000s. However, the files have been largely replaced by XLSX files since Microsoft released Excel 2007. Although XLS files are not as common, you may still receive XLS files attached to emails from co-workers or friends. Or you may find old XLS files on your computer that you need to update. File Viewer Plus is an excellent option for opening, modifying, and saving your XLS files.
