Count Rows in Excel on condition<a>AND {condition<b> OR condition<c>}

Question

no matter how hard I reconfigure COUNTIF and COUNTIFS I can't get the output to work, here is a table example :

I cannot get a function that will count Where Severity = High AND (Customer !="" OR Case Info !="")

In the table example I should get a return of 5.

The closest I have got so far is with =COUNTIFS('8.2'!C:C," High ",'8.2'!A:A,"<>",'8.2'!B:B,"<>"), But that only returns 3.

What excel function could do what I need?

Answer 1

With COUNTIFS() you will need to do three:

=COUNTIFS(C:C,"High",A:A,"<>")+COUNTIFS(C:C,"High",B:B,"<>")-COUNTIFS(C:C,"High",A:A,"<>",B:B,"<>")

Or as XORLX showed:

=SUM(COUNTIFS(C:C,"High",A:A,{"<>","","<>"},B:B,{"","<>","<>"}))

But this requires that the cells be true blank, no formulas that return and empty string

SUMPRODUCT is slightly shorter but it requires that you specify the data range to avoid unnecessary iterations as it is an array type formula:

=SUMPRODUCT((C2:C17="high")*((A2:A17<>"")+(B2:B17<>"")-((A2:A17<>"")*(B2:B17<>""))))

Or this one by XORLX, who has forgotten more about excel formulas than I will ever know:

=SUMPRODUCT((C1:C20="high")*((A1:A20<>"")+(B1:B20<>"")>0))
