Tableau Prep was used to shape, combine, and clean 50 different data sources into one consolidated data connection!

Using Tableau Prep to Shape, Combine, and Clean Dataīy the end of this post, you will be able to recreate this flow in Tableau Prep that pivots some columns to rows, then some rows to columns: This post uses the Rotten Tomatoes data source used to create my BLOCKBUSTER visualization to show you how to pivot columns to rows (pivot), rows to columns (unpivot), or both, in Tableau Prep 2019.1 or later. As long as you are a Tableau Desktop user with a Tableau Creator license, you can install Tableau Prep and do this yourself! You have been able to pivot columns to rows for a long time in both Tableau Desktop and Tableau Prep, but now it is even easier to quickly restructure an existing Excel report so you can start exploring it in Tableau right away.

Tableau Prep Builder automatically creates a My Tableau Repository folder structure in the documents folder. SRM may end the protocol server process of Tableau Prep Builder in case the computer resources are exhausted, and this does not have a recovery mechanism. Tableau Server Resource Manager (SRM) cannot differentiate between the Tableau Prep protocol server process and the Tableau Server protocol server process.
