Find the match between two lists and columns
I have two lists or columns. One with the answers made by some people (LIST_1) and the second with the correct alternatives (LIST_2). How can I, in POWER QUERY, return the number of lines that match?
I speak list or column, because I would imagine that finding the lines that coincide as a list would be the best way. But, if possible as a column, it can also be useful.
Sample
Hi, PietroFarias
let List_1 = {"E", "B", "C", "B", "E", "B", "C", "E", "E", "C", "A", "E"}, List_2 = {"A", "A", "A", "B", "C", "D", "E", "B", "D", "C", "A", "B"} in List.Count(List.Select(List.Zip({List_1,List_2}),each _{0}=_{1}))If my code solves your problem, mark it as a solution

Hi PietroFarias ,
Try this m code:
let
List_1 = {"E", "B", "C", "B", "E", "B", "C", "E", "E", "C", "A", "E"},
List_2 = {"A", "A", "A", "B", "C", "D", "E", "B", "D", "C", "A", "B"},
Match = Table.RowCount(Table.SelectRows(Table.FromColumns({List_1, List_2}), each [Column1] = [Column2]))
in

Hey PietroFarias ,
We can achieve this using this simple technique also:
Exepected Output:
Step1 : Add a conditional column
Enter the details as shown in the picture
- New column name= Result
- If Column Name = Students Answers (Column)
- Operator= Equals
- Value= Correct Answers (Column)
In the value's list Select a column
- Output = Correct
- Else = Not Correct
Then Click on OK
Result
If your problem is solved then please accept this as solution.
Thank you
