The course then moves into core cleaning skills such as fixing headers, removing clutter, keeping needed rows, managing data types, resolving locale issues, and handling conversion errors.

You will also append monthly tables, merge lookup data, combine all files from a folder, manage query dependencies, use parameters, and control refresh behavior.

Quality control is built into the workflow, with lessons on troubleshooting broken queries, adapting to changing source structures, validating results, and documenting transformation logic. After completing Excel Power Query: Cleaning and Transforming Real-World Data, you will be able to replace repetitive manual cleanup with structured, refreshable Power Query processes that make your Business reporting faster, cleaner, and easier to trust.
