New column with data from already existed column

Hello,

I have a query to add a new column (Data into this new column is from already existing column).I will try to explain it to you in clear below.

In the photo below in column 'K' whrer I have data related to category names X,M,W.

I want to make new columns with category name X, M, W beinging separated. 

For example I have to have column with only M values in it and same should be with X and W.

Do I have any leads ?

Thanks in advance.
