File extensions are related to the file format, which is a computer programming term that specifies how information is coded for storage in a computer file. In the case of Excel, the current default file extension is XLSX and has been since Excel 2007. Prior to that, the default file extension was XLS. The difference between the two - besides the addition of the second X - is that XLSX is a XML-based open file format, while XLS is a proprietary Microsoft format.
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.
