beginner level Python:- output XLS spreadsheet instead of using tabulate

[Gribouillis]

If there is a better way please comment

If the Excel file doesn't need special formatting, you can write a csv and convert to xls by running an external command from python, for example if you have libreoffice installed on your computer, the following should work:

returncode = subprocess.call("soffice --headless --convert-to xls ACI-Endpoints.csv")
if returncode:
    raise RuntimeError(('Conversion to xls failed for', 'ACI-Endpoints.csv'))

You can also convert to xlsx with soffice --headless --convert-to xlsx:"Calc MS Excel 2007 XML" file.csv
