Visual Scripting: "Write Data To Sheet"

Hello Visual Scripters, I would like to export a set of xyz coordinates of points to a csv file. 

 

I found the generated file in "C:\\Users\\XXXXXXX\\AppData\\Local\\Temp", but the csv is empty. 

 

Is there some other step needed to trigger the write or is there a particular format/syntax the tool is expecting at the input?
