What is a XLS file?
XLS is the proprietary spreadsheet format used by Microsoft Excel prior to the introduction of XLSX in 2007. It uses a binary file structure and supports formulas, charts, macros, and formatting.
XLS files remain widely compatible and are still used in many organizations. However, XLSX offers better performance and security.
How to open XLS files
XLS files can be opened using Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications. They support charts, formulas, and formatting.
To ensure compatibility and security, convert XLS to XLSX or ODS using AnyConv or within Excel itself.
