Exporting Revit Data to an existing excel doc

Hello guys,

Is it possible to export Revit data to an existing excel doc in dynamo?
Every time I run the script it deletes/overwrites everything I have in the doc.

Overwrite (boolean) is set to False

Hi @KingK, Could you share some screenshots?

the script is simple as I am just using it to test how it will work
I have also attached a screenshot of the excel sheet to give you an idea of what I am working with.

what I am trying to achieve - to export room data such as wall height, width, room number, name etc from revit into those columns in the excel sheet
