7/13/2023 0 Comments Tableau prep releases![]() Instead of building lookups or using different validation techniques in Excel, we can quickly build it in Tableau Prep. Furthermore, Tableau works well as a data discovery tool, provided that we are working on a small database within a small flow complexity. We can use Tableau Prep for creating a proof of concept or answering an ad hoc question within minutes rather than hours, which some of us are used to from other tools, especially those requiring large scripts. In order to change small case name-last name into a proper format, we have to write two lines of code that may not be very obvious for beginners (be on the lookout for a forthcoming blog post on this!).Īll of the above makes creating simple flows with straightforward transformations uncomplicated and quick. Tableau may also lack some simple commands like TitleCase(). However, it does have its downside – many transformations that can be simple in other tools are complex or even impossible in Tableau Prep. Additionally, in Tableau Prep we have a limited amount of tools (seven), which makes it fairly straightforward to understand what should be done next, especially in comparison to other solutions that can have hundreds of tools. If we compare it to coding in SQL, we can clearly see the advantages for our peers that do not work in an IT-related department (blog post on this topic coming soon). The fact that we can click on any step, follow the logic and adjust it when necessary makes Prep quite intuitive. Tableau Prep is perfect for data transformation beginners since its intuitive visual interface provides us with an easy-to-grasp step-by-step overview of the data flow. ![]() Those of us who haven’t worked much with data transformation before could feel overwhelmed using the more complex tools.
