Helpful wizard for Find duplicates rules and blocking keys

Since v 2.14 Data Studio users can now create Find duplicates rules and blocking keys by answering simple yes/no questions if you want to include email, phone number or any identifiers contained in your data.​​ This will generate the usual scripts (which can be further edited for more advanced use cases) containing the selected elements and fuzzy matching logic. For more technical users the edit script option is still available.

Have a look at the demo video how to use the rule builder wizard.
