XLS files are widely used in education and in work, although in 2007 they were replaced by the XLSX file format as the primary file type used for Excel spreadsheets.
Users can open XLS files with either Office for Windows or Office for Mac, and both these programs support features, including macros that have been written in Visual Basic. While applications like OpenOffice allow XLS files to be opened, some features may be limited. XLS files can also be opened on Android or iOS.
