Hi, I have a table with 27 colums with one called last name and 26 questions, like shown in picture. Since someone only answer some of questions and leave the blank for others. I want to calculate how many questions a person answer in a new column. How can I do that?
@Anonymous ,
You can unpivot the values using Power Query.
Select the name column and right click -> unpivot other columns, the result is:
NAME, ATTRIBUTE, VALUE
With this dataset you can easily count the blank values or nonblank values.
