I am trying to make it so I can add a new row once something is put in the description cell. (Sheet link is attached for reference.) I would want this to be so I could just keep adding as many rows as the invoice required. I think apps script and onEdit() would be the best way to do that? I'm just not sure how to implement as I am a beginner and through my google searching I haven't been able to piece anything together.
