What to expect

Power Query is a powerful tool for importing, cleaning and restructuring data from a wide range of sources. This course introduces you to the core workflow so you can automate preparation steps and bring data into Excel in a reliable, repeatable format.

You will learn how to connect to different data sources, apply transformations and reshape complex information using tools such as grouping, summarising, transposing and unpivoting. These techniques help streamline analysis and reduce manual effort, particularly when you work with large or frequently updated data sets.

The course also introduces basic Power Query formulas and the M language, giving you the foundation to customise queries and enhance data models through PowerPivot. By the end of the program, you’ll be able to build efficient, automated processes that support cleaner, more accurate analysis.
