XLS is the file extension of the Microsoft Excel spreadsheet. It is created in the versions of Excel prior to 2007. It is a binary format based upon Binary Interchange File Format (BIFF) and thus it stores information in binary format. It is capable of holding the spreadsheets either containing macros or not.
