A formula in Excel to count the number of rows where there is a date in column 'K' but column 'N' is blank?

Question

I am a little rusty to say the least and in Excel I would like to create a formula that counts the number of cases that have been closed without a certain stage taking place.

So, the formula would need to count the number of rows where there is a date in column k, but no date in column n (the cell is blank). Any help would be appreciated. I have had a go with COUNTIFS and SUMPRODUCT but I'm not getting anywhere.

Answer 1

Try this

=COUNTIFS(K:K,">0",N:N,"")

that's counting rows where K is greater than zero but N is blank [""]

Answer 2

If you can use another column try this formula, for every row of the column:

=IF(K1>0,1,0)*IF(N1="";1;0)

then you have to sum column values.

Instead of K1>0 you can use two cell for date so you can count cells within a range of date.

Answer 3

首先，尝试类似：

=SUMPRODUCT((K1:K100<>"")*(N1:N100=""))
