Excel binary workbook.

A .xlsb file is a saved Excel spreadsheet file, generated with Microsoft Excel 2007 (or later). A .xlsm file allows the use of macros (VBA) in the spreadsheet.

Unlike a .xlsm file a .xlsb file is saved in a binary file format. This makes it smaller and more effcient than the corresponding .xlsm file would be.
