Conversion of xlam files to xlsb file format

Excel Add-ins (.xlam) cannot be directly converted to workbooks (.xlsb) or spreadsheets (.xls, .xlsx), which means that xlam to xlsb conversion is unlikely. However, what you can do is to import the add-in to Excel and use the extra function or feature to change existing workbook or create a new one.
