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.
The .xlsx and .xlsm formats store almost all components of the workbook in XML format, i.e. specially formatted text. This makes it easy for other programs to read and even manipulate the contents of the workbook without having to start Excel. The .xlsb format stores the core components of the workbook in binary format. You need Excel to read and edit it. So the .xlsx and .xlsm formats are more open. For small and medium-sized workbooks, the difference in size and in reading/writing speed between .xlsx/.xlsm on the one hand, and .xlsb on the other hand, are not significant.
