Frequently asked questions
DAX or Power Query — which should I use?
As a rule, shape data as early as possible: use Power Query for row-level cleaning and columns that never change, and DAX for calculations that must respond to slicers and filters.
Can it generate a date table?
Yes. Ask for a calendar table with the fiscal year start you use and you will get complete code.
