We have a dedicated area of the forums for discussions related to TabPy. I have moved this thread to that location - Tableau External Services
There are members of the Tableau team and other users that monitor this area for questions related to the various External Services, TabPy, R, and MatLab.
It would help to know a little bit more about your use case here. Is you end goal to display a text list of the tools a user has access to?
A simpler way to do this may be to actually connect Tableau to the excel file and have a user enter a name as a parameter to filter it.
Are you able to share a workbook with this dataset?
Unfortunately, I can't share a workbook with this dataset. And later I was able to achieve what I wanted in the dashboard.
Since it looks like you solved the issue, I'm going to close this tab.
Would you mind sharing the steps you took to achieve your result?
