DAX Distinct Strings looking in column of Lists - powerbi

Question

I'm trying to do a DISTINCT function with DAX, however looking within list values and not just the column value. Sample data (sorry for the formatting):
Name Word List
Bob {aye, bee, cee}
Bob {aye, bee, cee}
Jim {dee, eee, eff}
Jim {dee, eee, eff}
Ray {aye, bee, cee}
Ray {dee, eeee, eff}
Desired Measure Output
Distinct Words for Jim: 3
Distinct Words for Bob: 3
Distinct Words for Ray: 6
Is there a way for the measure to look through the list and count distinct values?

Answer 1

This doesn't really answer your question how to count distinct in columns of lists but is a workaround to get the desired results.
I would use the query editor and Split Column > by delimiter (under the Home tab) and Replace Values (under the transform tab) to get your table to look something like this:
Name 1 2 3
Bob aye bee cee
Bob aye bee cee
Jim dee eee eff
Jim dee eee eff
Ray aye bee cee
Ray dee eeee eff
After that I would select all columns except Name and use Unpivot Columns, which would make your table look like this (after removing the Attribute column).
Name Word
Bob aye
Bob bee
Bob cee
Bob aye
Bob bee
Bob cee
Jim dee
Jim eee
Jim eff
Jim dee
Jim eee
Jim eff
Ray aye
Ray bee
Ray cee
Ray dee
Ray eeee
Ray eff
By simply dragging the Name and Word columns into a Matrix visual now you would get distinct count.
If you have a lot of data you could instead Group By on name with Count Distinct Rows as Operation already in the Query Editor and you would get a table that looks like your desired result.
