Updated March 10, 2017. A file with the XLSB file extension is an Excel Binary Workbook file. They store information in binary format instead of XML like with most other Excel files (like XLSX). Since XLSB files are binary, they can be read from and written to much faster, making them extremely useful for very large spreadsheets.
However, if you run the code in Excel 2007 or Excel 2010, the code will look at the file format of the parent workbook and save the new file in that format. If the parent workbook is a macro-enabled file (.xlsm) and there is no code in the new workbook, the new file will be saved as a macro-free file (. xlsx).
