Is there a node that does the same thing but works with files as input?

Unfortunetely i don’t know anything about python… so i guess i’ll have to load the families into a project. Create the types from there and then use that method you thought me before to export those familys

Managed to do that. But how do i delete a family type?
Since all the familys are a copy from one family. they all have one type in common. I need to mass delete it.
Thanks for your help!

I think that the idea for the solution marking is that we do it in one way that future user’s come to the topic and quickly find the solution for the issue.
Being so, i marked my self as the solution, because it had the most straightforward way of troubleshooting what the topic intends to do.
It doesn’t mean i have any credits about it. Of course it belongs to you @erfajo
