I am actually using Tableau Software Desktop and saving my workbooks to .twbx (tableau data extract + tableau workbooks) and I need to refresh my tableau data extract ( not the view ) every 4 hours. I found out that there are plenty of ways to do it with Tableau online but none with tableau desktop. What I am thinking of, would be to send the keys in a power shell script to Tableau to automatically refresh the .TDE ( which is connected to a psql database ).

Thank you for helping.
