Create multiple project parameters on diffrent categories from an excel file

Hello Dynamo-Community,

i am pretty new to dynamo and programming. I want to create multiple project parameters on diffrent categories bases on an excel file.

I tried to solve my problem with a loop. It didnt work, because the loop just gives me the “last result”.

Here are my nodes:

I would be very happy, if i could get any help!

Thank you in advance
