Starting in Tableau 2019.1, you will no longer be able to create legacy connections to Microsoft Excel or Text files. You can still open and work with existing workbooks and data sources that use legacy connections until 2019.4. In 2019.4, all support for legacy connections will be removed. Because Microsoft no longer supports the underlying technology that legacy connections are based on, Tableau must discontinue support for legacy connections.
