Before raw data enters your model, use Power Query to transform and clean it up. It's perfect for importing, filtering, merging, and shaping data.
Create relationships, calculate columns, and use DAX measures to specify business logic using Power Pivot for data modeling.
To put it briefly:
- "Get and clean your data" is the Power Query value.
- "Model and analyze your data" is the Power Pivot.
- For best performance and maintainability, combine the two.
