What is Power Query?
Power Query is the data transformation engine inside Power BI used to connect, shape, and clean data before it is loaded into the model. It provides a graphical interface for common operations like filtering rows, renaming columns, and merging tables, and it records each step so the transformation is repeatable. Behind the scenes, it generates M code that runs whenever the data is refreshed.
