Exporting schedule list to Excel but paramter with "Tick" option shows empty in Excel

I have made a script that export the Revit schedule in active window to Excel. Its fine but now comes some paramaters in Revit with “Tick” option and when i try to export this schedule to Excel . Instead of “Tick” shows empty in Excel and when the parameter is not checked in Revit and in schedule then comes “No” in place. Is there a way to export “Yes” when its ticked. See images attacheda1

your boxes are not checked,
Either you things all the boxes that are by default checked
either you bypass it as follows:

Yes you were right. They were not properly checked and when i check it then coming “Yes” in Excel. Thanks
