Data preparation tools for Tableau

Looking for data preparation tools for Tableau? This article presents a list of data preparation tools that work particularly well with Tableau, enable self-service data preparation for users that don't have advanced SQL skills, run on-premise and cloud, and connect to core databases, such as Oracle and SQL Server.

Why data preparation tools for Tableau?

Tableau's data source interface allows us to do some basic data preparation tasks, including simple joins, unions, filters, data type changes, and various other things. However, if you have tried using Tableau on real data, you definitely have got to the point where you needed to do more. Here are some example scenarios to help you justify your requirements for data preparation tools for Tableau.

For example, let's say you are working on an analysis that involves 10 different database tables. All of these tables are huge, with over 20 columns and millions of rows of data. If you are a general Tableau user, without the advanced SQL skills to match the task, you are going to end up with a massive Tableau workbook with 200+ dimensions and metrics. This will load very slowly, and you really won’t get very far with it.

Another scenario: working with derived tables. It isn't possible to create sub-queries using the Tableau data source interface. In cases where you need to join the result of a query to another table, you have to write custom SQL. This limits user control over the structure and granularity of the dataset.

There are other reasons to use data preparation tools for Tableau. For example, you may want to bring in a data type not recognized by Tableau, pivot data in a very specific way, work around missing data in your data source, etc. Data in the real world is complicated. It is frequently dirty and inconsistent. Repeating the same cleaning tasks, workbook after workbook, is time-consuming. If you are dealing with data preparation issues, you may need a data preparation tool for Tableau.

A full list of data preparation tools for Tableau

The choice of data preparation tools is huge. If you google "ETL tools", "data preparation tools", "BI tools", "data cleansing tools", and so on, you will find a lot of options. Which one to choose?

To compile the list, I've used the following criteria:

  • Self-service data preparation Don't have advanced SQL skills? No problem. These tools allow you to work with data using a drag-and-drop user interface.

  • A native integration with Tableau You don't want to have to find workarounds to bring the data into Tableau, once it's ready. The ideal solution is a data source on Tableau Server, Tableau Online or on your desktop.

  • Verified by Tableau Tableau has a technical partners program. They admit to the program the tools that complement Tableau and provide functionality that Tableau doesn’t offer.

  • Works behind firewall You may be comfortable with loading data into the cloud, but in case you are not, these tools can run on-premise.

  • It's more than an Excel plug-in You will be able to connect to core databases, such as Oracle and SQL Server, as well as other data sources.

Without further ado, here is the list of data preparation tools for Tableau, listed alphabetically.
