Not sure I completely understand your question, but Tableau isn't like VBA, it doesn't give you a button option that you can then assign an action to. (Sometimes I too wish for this.)
Yes you r right Shawn..
I will not encourage this tool for my client.
Its simply wasting of my time.
Sorry Tableau doesn't work for your import/export needs, but it really is a very cool Data Visualization tool. If you have need of data viz, it's the best on the market. Hope you'll come back.
