Alteryx is able to read qlikview data files via the normal input tool... or at least one type (qvx). You can then use the output tool to create tableau data files (tde). However, while it is possible to move the data the visualizations, as far as I know, cannot be converted.
Just the data- read in the Qlik file and output a TDE. You would still need to use Tableau desktop to build the dashboard itself based on the data - no way around that. But luckily, Tableau is much faster and easier to use than Qlik, so that part should go quickly.
