I saw this article : http://www.andrewfitz.net/one-day-at-a-time/testing-out-office-forms-and-power-bi
I don't know how create connection to Office Forms? I know only how connect to Excel survey in Office365 or in Onedrive.com, but office Forms are very nice to use in my job. I'm a teacher :-) .
Thanks for your answer.
We are not able to directly connect to Office Forms from Power BI. What we can do is to connect to the Excel survey of Office Forms in Office 365 or OneDrive, then create visualizations.
