Matrix counting blank values in table

[Anonymous]

Hi! 

I'd like to count all blank values in all columns in a data table and show them in a matrix, rows being the column names and one column showing the number of blanks in each column. 

Is there a way of writing a measure that handles counting blanks without specifying the column in the DAX-formula (doing this requires creating a measure for every column). 

This is an example: 

Data table: 

Name 1	Name 2	Name 3	Name 4	Name 5
1	2		1
1	1		2	2
	2		3

Displayed like this: 

Name of column	Number of blanks in table (measure)
Name 1	1
Name 2	0
Name 3	3
Name 4	0
Name 5	2

Can this be done?

Hi @Anonymous 

You can try the Power Query as in the video below.

Absolutely brilliant! 

Worked like a charm and very elegant. This worked with Direct Query as well 

Thanks so much!

@Anonymous best approach would be to unpivot your table and then one measure can take care of this. To unpivot, go to Transform Data

add index column

select index column

right click, select unpivot other columns

you will have two new columns, Attribute and Value

and you can use COUNTBLANK() DAX to count blanks and on table visual add Attribute column and Measure and you will get the result.

Would appreciate Kudos 🙂 if my solution helped.

Thank you for the solution. 

Looks like this could work for projects using "Import", but I'm having difficulties as I'm using Direct Query (forgot to mention in my post).
