Power Query Beyond the Ribbon: Types

Some time ago I gave a session on SQL Server Days about Power Query. I really enjoyed speaking there. The title of the session was “Power Query Beyond The Ribbon”. I have to admit a major strength of Power Query is that you can do pretty much everything only by using the ribbon. However this doesn’t mean that learning something about M, the Power Query Formula Language, is a waste of time. With M you can solve some complex problems, automate parts or simplify your solution.
