Here is an interesting challenge. With a column of names, and a column of musical preferences and each person has multiple music preferences, how can the preferences be split such that you have TRUE if a person has that preference, and FALSE if a person does not?
One twist: what if there's a person added/removed or a music preference is added/removed?
This challenge came from Chandeep Chhabra at the Goodly YouTube channel.
My solution in Power Query includes:
Left Outer Join with 2 criteria
Cross Join
Conditional Column
Pivot Don't Aggregate
All handy features that can help you create dynamic solutions in Excel and Power Query.
