To output data from Alteryx to Tableau is incredibly simple, Alteryx has the output File Format of a TDE file.
Just select your data, drag in an Output tool and set the file type to be Tableau Data Extract (tde). Alternatively enter a .tde file name into the ‘Write to File or Database’ input box and it’ll default to a Tableau Data Extract File Format.
If you don’t have a tde file already created, Alteryx will create it for you – although this isn’t 100% clear. Type the name and location you want for your Tableau Data Extract in the ‘Write to File or Database’ location and Alteryx will create and put your tde file in that location.
In the Output Options you can now append to an existing Tableau Data Extract file, meaning you don’t need to recreate the entire tde every time, particularly useful if you have incremental data. If not then go for the Overwrite Existing Extract File (Create if does not Exist) option.
