I just published the node on Hot Gear packages.
For Normal Family Type Parameter / Instance Parameter you just need insert the category and excel file path, it will export all family include of the Category / Element in the Document.
For System Family you need to insert the Element Types and excel Path.
If File Path is no selected it will auto open the new excel file.
The next will be the Import of the excel but it’s hard to all in one auto fill in the right place with the right data format.
