Using data from Excel to populate Label Parameters in Revit

Hi @tkuhn89

Welcome on Forum!

You just have to use Read.Excel node, get the values, write the values using Element.SetParameter node.

I would suggest for a begginer to have a look at some basic information about dynamo. Below are the links.
