Extensions in Excel
Excel File Extensions are there to identify the file format. In computer operating systems file extensions are to identify the file type for the operating system so that it runs and opens the file with the specified format.
If you observe at the end of the file name you will see the extension of that file.
In the above image, extensions are XLSX, XLSM, XLSB, XLS, and XLAM.

XLSX does not support the macro code. In order to run the macros, you need to save the workbook as a macro-enabled workbook.
