Rhino adds number after attribute user text with every csv file upload

Hello community,
maybe someone has a hint for me: I would like to implement attributes to some Rhino objects by adding attribute user text. Since every object should have the same list of attributes, I wanted to give them all an empty list first and them upload another csv file once I have my values. (For some objects I don’t have the data right away, so I’ll probably have to update every object individually.)
I did a test run and saw, that once I upload a second csv file with the same attributes, Rhino does update the values to the according attributes without creating any duplicate attributes, but it changes the attribute text by adding a (1) after the original text. Example:
name : __
ID : __
changes to
name (1) : Peter
ID (1) : 1234
when I upload a csv file that looks like this:
name,Peter
ID,1234
Is there any way to avoid that number?

Best,
Carina

PS: If someone has a good tutorial on how to extract data via Grasshopper from an excel file and add it as attribute user text in Rhino, I’d really appreciate it. :slight_smile:
