Now wait for the extract to be created, how long you’ll wait depends on the database technology you’re using, network speed, data volumes that sort of thing. Tableau will as where you want to save the extract – choose any location to save the file, although Tableau will probably direct you towards ‘My Tableau Repository | Datasources’ which is just fine too! After you have connected to your data, go to the DATA menu and choose EXTRACT DATA – then accept the defaults on the dialog box (although more on this later).
