Remarks
If your template file is the new Office Open XML (.xlsx) format, you can pass it into the ExcelTemplate.Open method just as you would a BIFF8 (.xls) Excel file. You will need to remember to give the output file a ".xlsx" extension when you call Save, as ExcelWriter cannot convert .xlsx files to .xls.Examples
