In this video, I’ll show you how to stack multiple columns into a single column in Power Query using the List.Combine function. You’ll learn how to convert columns into lists, merge them together, and turn the result back into a clean table. It’s a simple but powerful M language trick that can save you a ton of manual work while cleaning your data in Power BI or Excel.
