如何在Excel中的sumproduct中动态选择单元格范围

Question

I am trying to use Sumproduct dynamically on a sheet that will be updated regularly.

My motive is to not manually select the columns ( ie not to use the shift key and down key to select the range A2:A6 as seen in the attached snapshot)

I want to have the formula "=SUMPRODUCT(--(A2:A6="TX"))" pick up the A2:A6 dynamically since my data in worksheet say A is everchanging. So that when the data has grown to A8, it can be somehow picked up dynamically than manually using the keys.

Can this be done? Please let me know if my question is not clear.

Answer 1

Yes, you could define the range dynamically. However, given your current formula, I see no reason why you should not switch to COUNTIF here, ie:

=COUNTIF(A:A,"TX")

a function for which the use of entire column referencing ( A:A here) has no detriment to performance (which is not at all the case with SUMPRODUCT ).

Shitty recommendations guy, here.

Can you insert a new line above all in your sheet? You could put it really wherever you want and you can even hide it, the first line just works for me.

If you can, just make it an "count.values" function on the entire column with an appropriated subtraction to adjust the count to the right length of your data. Eg Removing this auxiliary cell value plus a header would be "=count.values(A:A)-2".

Later, on your VBA, you could retrieve this value to a variable and concatenate it to your main function. Lets say you made the auxiliary on cell A1 (coordinates 1, 1)

Dim auxLine As Integer auxLine = cells(1, 1).value whatever.formular1c1 = "=SUMPRODUCT(--(A2:A" & auxLine & ="TX"))"
