What is Custom Columns?
Custom columns are new columns created in Power Query using a formula written in the M language, giving more flexibility than the conditional column builder. They allow calculations that reference multiple columns or use M functions not exposed in the standard UI. This is a common entry point for users moving from the graphical interface into writing M code directly.
