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.
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.
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.
