From there, I’d want to take a sum of sales in each respective region, and with that, I could deduce which category has the highest sales in each region. For example, if I want to know which category in my dataset is the most profitable in each region, I would need to start by splitting the data by each region. The first thing I like to do is create a plan of what the overall goal I want to accomplish is and break that down into bite-size chunks. Now that we’ve covered how to connect to data in Tableau Prep, we are ready to dive right into some of the different tools you can use to build out a workflow.

For this exercise, we’ll be working with the Sample Superstore dataset provided by Tableau. This menu is packed with many different data connectors, which allows you to connect to basically any form of data storage you may be working with, from standard Excel documents all the way to data warehouses.
