Count unique text values based on criteria in other column


I have two columns titled "Company" and "Department", example below. The third column is what I would like to create, but I am unsure how. I want the third column to show the number of departments for a given company, and only show that number in the first reference to the company.

Solution

  • Try this in D2 and fill down.

    =IF(COUNTIF(A$2:A2, A2)=1, SUMPRODUCT((A$2:A$999=A2)/(COUNTIFS(B$2:B$999, B$2:B$999&"", A$2:A$999, A2)+(A$2:A$999<>A2))), "")
