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.
