Conversion of xlsm files to xlsb file format

xlsm to xlsb conversion is pretty much just resaving between two different MS Excel types. You can easily re-save .xlsm spreadsheets to .xlsb files using the File ► Save as.. function in Microsoft Excel. Some other spreadsheet programs may also offer this conversion, but it is always best to use the original program because of compatibility reasons and special formatting.
