I’m encountering the above error when i try to use the import sheets from excel task. Everything seems fine until:
I blocked out proprietary information, in the image the important thing to note is the lack of headers at the top of the column. Pulling down on the little drop down arrow yields . Selecting this for each header results in a bunch of sheets created, but not named nor numbered beyond the default Revit naming sequencing.
Showing the top few lines of my excel file.
Thank you!
