Import Data from excel to Revit, triggerd by ElementId, how?

@Nick_Boyts ,

steps are:

1.) make it run
2.) make it right

i changed the lacing( to longest) too at the end of the transaction. I have to check result, but revit collabes for now…

in my proposel i have 55 vales/Parameter to change…

finally i will change 80.000 elements with 25 Parameters… how can i handle that, when revit has issues even now ( i test in adetached model)
