I'd like to find how to use the COUNTIFS function in excel to count the rows in a spreadsheet while ignoring duplicate values in a separate column. Here is a sample of the data:
[]
I would like to count the number of rows that are "One" on status and "Blue" on category. However, I only want to count the duplicates for these respective values in "ID" once.
Here's what I've tried:
=SUM(IF(FREQUENCY($A$2:$A$12,$A$2:$A$12)>0,1))
Same problem as the previous example. - this works for giving me the number of duplicates in column A, but I can't work any IF statements in effectively.
=IF(B2:B12="One",IF(C2:C12="Blue",SUM(IF(FREQUENCY($A$2:$A$12,$A$2:$A$12)>0,1))))
When I add IF statements in, I get the same number as the earlier formula.
For your copy/pasting pleasure:
ID Status Category
1423 One Blue
1423 One Blue
1423 One Red
5124 One Blue
5124 One Blue
2341 Two Blue
1111 One Red
1212 Two Red
1212 One Blue
1111 One Red
5124 One Red
The ideal result would be 3.
There is a standard COUNTUNIQUE method using SUMPRODUCT and COUNTIF functions; (e.g. SUMPRODUCT(1/COUNTIF(A2:A12, A2:A12&""))
). This can be expanded to include conditions by changing to a COUNTIFS function but care must be made to ensure that no #DIV/0!
error can occur.
In E4 as a standard formula,
=SUMPRODUCT(((B2:B12="one")*(C2:C12="blue"))/(COUNTIFS(A2:A12, A2:A12, B2:B12, "one", C2:C12, "blue")+((B2:B12<>"one")+(C2:C12<>"blue"))))
The numerator of the division operation provides half of the conditional processing. The COUNTIFS denominator of the division operator must be the opposite (non-zero) of the numerator when the numerator is zero.
