So I want to add a button in my text area in Spotfire which will open an excel file (that is connected to my spotfire visualisation) or at least to a network folder with that file. 
I believe I can write an ironpython script just to open that file and make changes. How will I do that? 
Update: 
After some googling I have tried to run a simple script smth like: 
t=open('D:/data/folderA/folderB/file.xlsx','w')
To avoid problems with "/" or "\", I also tried importing os
import os
t=open('D:','data', 'folderA', 'folderB', 'file.xlsx', 'w')
Neither of these work.
For those who is still struggling to find the solution, it turned out to be simpler than I thought it would. 
from System.Diagnostics import Process
Process.Start(r 'start c:\test\abc.xlsx')
