A complete picture of your data

Three coordinated views let you see familiar row-level data, profiles of each column, and your entire data preparation process. Pick which view to interact with based on the task at hand.

Immediate results

If you want to edit a value, you select and directly edit. Change your join type, and see the result right away. With each action, you instantly see the result, even on millions of rows of data with smart sampling. Tableau Prep gives you the freedom to re-order steps and experiment without consequence.

Smart, so you can work faster

Use smart features to fix common data prep challenges. Tableau Prep employs fuzzy clustering to turn repetitive tasks like grouping by pronunciation into one click operations.

Connect to more data

Connect to data on premises or in the cloud, whether it’s a database or a spreadsheet. Access, combine and clean disparate data without writing code. Tableau Prep intelligently pushes operations down to the database when possible, letting you take advantage of existing database investments for fast flow execution performance.

Before it was always numbers in rows and columns. Now I’m eager to see when I do a new analysis, because it's so much easier to actually see the trends, the story, and the power the data brings.
