We have bumped into the same issue as you had before when integrating Marketo and Tableau, so we decided to extract Marketo data to SQL Server database, then connected database and Tableau.
We have tried several data extraction tools including the tool you mentioned above, but they didn't resolve our data integration problem. Therefore, we have developed our own data retrieving tool called Data Loader for Marketo(DLM) which allows you to sync Marketo data to the database without any coding. We invite you to visit our website to have a free trial of DLM and see if this could solve your problem.
