Hi guys This is suvir here,i would like to create xcel sheets for multiple schedules when i run the script the BB data node shows output null
i have installed revit 2025 version and also same version of dynamo
error

Are you providing a matching list of sheet names? Have you opened the custom node to troubleshoot any root issues there? Do you have Iron Python installed? Is there a reason you’re using Bumblebee instead of the out of the box nodes?

Hi @suvirRZPH6

in addition to @Nick_Boyts 's answer, BumbleBee package not yet updated for Revit 2025 (.Net 8)

see here

for information, the switch to Net 8 (.Net Core) means that we can no longer use directly assemblies in the windows GAC (like Excel Interrop)

I have the same problem, when can we expect an update in package BB? I heard from my intern technical department that it was really huge change in API from revit 2024 to 2025. So the same dynamo script is working well in 2024 but in 2025 does not :frowning:

I don’t know if @Konrad_K_Sobon has plans for an update, but you could ask on his GitHub: GitHub - ksobon/Bumblebee: Excel interop for Dynamo

He also has a Patreon linked off his website where you might be able to sponsor an update: https://archi-lab.net/membership/

In the meantime you can also export to CSV and incorporate the data via link.
