How to create a specs spradsheet in Excel

Hello everyone,

I have to create a specs spreadsheet and I would like to use Dynamo to connect the data between Revit and Excel. The problem is, the definition “writes” the information about all the INSTANCES that are in the Project, not only the TYPES i’m using. Here is the definition I’m using and the result that I get.

Any idea?

 

Thanks a lot
