If you have Tableau on your actual machine, well, you need to make sure there's nothing there to mess with your script when you run it. I run Tableau Desktop on a virtual machine, and my script will only work if I'm actually logged in to the machine (otherwise it will not run the keyboard commands). It's not only a non-elegant solution, but a very unstable one too. twb file (if not already open), bring it to front, give an alt + d + x command (refresh all extracts), hit enter, wait for some time (in seconds, didn't figure out how to discover if the process is done), hit enter again, alt + f + k (export packaged workbook), some shift+tabs to go to folder prompt, enter the path, a few tabs to get to name prompt, enter the name, enter again, voila So I went to a non-elegant solution, used win32 api to make a script to give keyboard commands. twbx automatically (which is probably what you want to do. tde files, but yet you'll not be able to generate a. Extract data API can be used (with lots of effort) to update (replace).
While I don't have it, I didn't find any "reasonable" solution for the problem. The final solution is going for Tableau Server. Have exactly the same problem, only I have to update hourly my database :)
