I have not found any other reports of the error occurring with the extension. I would reach out to the creators of the extension to get some additional assistance: https://www.theinformationlab.co.uk/
If you found a workaround or root cause of the behavior please share it with the Tableau Community to help others that might find this thread.
I am experiencing the same issue with the Export All extension. Just wanted to know how you approached this problem and if you heard anything back from Craig. Thanks!
I am facing the issue with the Export All extension. Have you made any progress on getting a resolution or work around?
Sorry for throwing out another "Export All" question, but has anyone else had trouble getting the data to open up in an Excel window. When I click on the "export all" button, I get the data that I selected in the sheets and columns that I selected in the "configure" window, opening up in a window that says "tableau" on the top, not excel. It is as if the button does not have permission to open Excel. Any ideas?
Are you trying the extension on Desktop? This extension works only in Tableau Online or Server.
Lets me know if you made working,
