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 2019.2. In 2019.2, 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.
There are, however, alternatives to using the legacy connection that are outlined in this article. You can use:
- Tableau Prep
- Microsoft Access to link to data in Excel
- Other Databases (ODBC) connector
Note: Legacy connections have never been supported on macOS.
Use Tableau Prep to reshape data
Connect to your Excel sheet or Text file using Tableau Prep to reshape your data or to connect to a custom SQL query. For more information, seein the Tableau Prep Help.
