Some quick searching turned up this page: http://www.spss.com/drivers/clientSPSS.htm
However some sites declare that this only supports bringing data into SPSS, and does not support querying data from SPSS files. Even if the driver above does allow ODBC connections to SPSS files, I do not know if the ODBC driver and supported SQL follow their respective standards, as is required for connections from Tableau. Tableau will warn about any missing or incorrect functionality, but in many cases you can still proceed to create an extract.
If you are able to get this working please post your experience here. Good luck!
I am curious on this very topic - can SPSS data be visualized/imported in Tableau?
Could you tell me advantages of Tableau over SPSS?
