Counting NonBlank Cells across multiple columns

Hello House, I have a dataset where I used "SplitColumn by Delimeter" to split a particular column into several columns. Now, I will like to have a calculated column that will count the number of ce...

Anonymous I would recommend unpivoting those columns in Power Query. However, if for some reason you need them in multiple columns, you could use MC Aggregations:

https://community.powerbi.com/t5/Quick-Measures-Gallery/Multi-Column-Aggregations-MC-Aggregations/m-p/391698#M129

MC Count Blank = 
VAR tmpCol1 = SELECTCOLUMNS(Data,"Column",[Column1])
VAR tmpCol2 = SELECTCOLUMNS(Data,"Column",[Column2])
VAR tmpCol3 = SELECTCOLUMNS(Data,"Column",[Column3])
VAR tmpCol4 = SELECTCOLUMNS(Data,"Column",[Column4])
VAR tmpTable = UNION(UNION(UNION(tmpCol1,tmpCol2),tmpCol3),tmpCol4)
VAR tmpValue = COUNTROWS(FILTER(tmpTable,ISBLANK([Column]))
RETURN tmpValue

Thank you very much for your quick response. This is appreciated. 

I actually do need the splitting in the multiple columns hence this request.

When I copied and edited the syntax you suggested, it gave me some error. Please see the screenshot below

 

 

I think the error is from second to last step of the formula (ISBLANK([Column]))):

MC Count Blank =
VAR tmpCol1 = SELECTCOLUMNS(MAD,"Column",[Please mention all the food your child ate between yesterday and now, Day&Nigh.1])
VAR tmpCol2 = SELECTCOLUMNS(MAD,"Column",[Please mention all the food your child ate between yesterday and now, Day&Nigh.2])
VAR tmpCol3 = SELECTCOLUMNS(MAD,"Column",[Please mention all the food your child ate between yesterday and now, Day&Nigh.3])
VAR tmpCol4 = SELECTCOLUMNS(MAD,"Column",[Please mention all the food your child ate between yesterday and now, Day&Night.])
VAR tmpTable = UNION(UNION(UNION(tmpCol1,tmpCol2),tmpCol3),tmpCol4)
VAR tmpValue = COUNTROWS(FILTER(tmpTable,ISBLANK([Column]))
RETURN tmpValue

    Anonymous I'm on my phone so hard to see error message. But may try

    COUNTROWS(FILTER(tmpTable,[Column]=BLANK()))

    Anonymous There is just a missing ) in the line before RETURN:

    MC Count Blank = 
VAR tmpCol1 = SELECTCOLUMNS(Data,"Column",[Column1])
VAR tmpCol2 = SELECTCOLUMNS(Data,"Column",[Column2])
VAR tmpCol3 = SELECTCOLUMNS(Data,"Column",[Column3])
VAR tmpCol4 = SELECTCOLUMNS(Data,"Column",[Column4])
VAR tmpTable = UNION(UNION(UNION(tmpCol1,tmpCol2),tmpCol3),tmpCol4)
VAR tmpValue = COUNTROWS(FILTER(tmpTable,ISBLANK([Column])))
RETURN tmpValue

      Thank you Greg_Deckler . The syntax returned aggregate value for all rows. This is not what I want. Please see screenshot below:

       

       

      For this screenshot, you would notice that only the first column has values while the rest has are blanks. The figures here should 1. Please can you help out.

        Anonymous Maybe:

        MC Count Blank = 
VAR __Table = SUMMARIZE('Table',[Column],"__Column1",MAX([Column1]),"__Column2",MAX(Column2]),"__Column3",MAX([Column3]),"__Column4",MAX([Column4]))
VAR tmpCol1 = SELECTCOLUMNS(Data,"Column",[__Column1])
VAR tmpCol2 = SELECTCOLUMNS(Data,"Column",[__Column2])
VAR tmpCol3 = SELECTCOLUMNS(Data,"Column",[__Column3])
VAR tmpCol4 = SELECTCOLUMNS(Data,"Column",[__Column4])
VAR tmpTable = UNION(UNION(UNION(tmpCol1,tmpCol2),tmpCol3),tmpCol4)
VAR tmpValue = COUNTROWS(FILTER(tmpTable,ISBLANK([Column])))
RETURN tmpValue
