Earlier this year, we launched Tableau Prep—our new data prep product that helps you combine, shape, and clean your data for analysis. It’s been incredible to see the community share their knowledge throughout the beta period (when Tableau Prep was code-named Project Maestro) and in the months following the Tableau Prep launch.

Tableau Prep has a lot of powerful features and like any new product, it takes time to learn the ins and outs. We’ve curated a list of Tableau Prep resources from across the Tableau website and the Tableau Community to help you jump-start your learning.
