Technical requirements
To follow along with the recipes in this chapter, you will require Tableau Prep Builder. We'll use sample Excel files supplied in the book's GitHub repository, so there's no need to connect to a database. In each recipe, however, you can replace the suggested sample input data source with any connection type that suits your scenario.
The recipes in this chapter use sample data files that you can download from the book's GitHub repository: https://github.com/PacktPublishing/Tableau-Prep-Cookbook.
