I am exploring Tableau for the office, and I have received a series of requests asking whether Tableau dashaboards can be published to internal SharePoint site. The answer would be definitely "Yes" should we are equipped with Tableau Server, but we don't have a Tableau Server unfortunately.
After online research, I noticed there were posts mentioning this question before, but they have been removed. I could not find any possibility other than procuring a Tableau Server. I would be great if someone experienced could give me some advice on this question.
I believe you can not integrate your dashboard to your share point website until unless your dashboards are not publisher in Tableau server (Public, Online & in house).
To publish the same in your share point you need Tableau Embedded View. For more detail please refer to below url.
