Hi Biff, Mike,

I have same kind of problem. I need to get unique values in a column using sumproduct. I have lets say column named ranges as BU and Subscriber. Both are text.
I tried
=SUMPRODUCT(1/COUNTIF(Supervisor,Supervisor), -- (BU="NA"))
which gives me result in fractions
and
=COUNT(1/FREQUENCY(IF(BU="NA",Supervisor),Supervisor))
which gives result as 0. Bothe are incorrect

Pls help

I have a summary sheet and a list of names, in ColumnC, on this sheet. I’m
trying to figure out a way to find a match in names in ColumnC of Sheet2, and
then count unique numbers, in Column G, for these names. I was experimenting
with this:
=SUMPRODUCT((Sheet2!$C$2:$C$1000=C57)/(COUNTIF(Sheet2!$G$2:$G$1000,Sheet2!$G$2:$G$1000&" ")))

This comes pretty close, but the numbers are off a bit.

Any idea how to do this?


Thanks,

Hi,

I cannot see anything wrong with the formula. In what way are the numbers
'off a bit'?

Hi,

This 'may' be a slight improvement to eliminate blanks being counted

=SUMPRODUCT((Products!C2:C1000=C57)*(Products!G2:G 1000<"")/COUNTIF(Products!G2:G1000,Products!G2:G1000&""))

Well, the results are just wrong. For one guy, named Ryan, not me though,
the result should be 32 unique numbers on Sheet2. The formula is giving me a
result of 30. I know this because I used the Advanced Filter to copy/paste
uniques to a new sheet. Also, some of the results are fractions, and I can
see this when I increase the decimalization. I should never have 12.33333
unique numbers; I should always have a whole number. I guess this is a
result of the division operator.

As I mentioned before, it is close, but not right.

Any other thoughts?

Thanks,

Hi,

I don't doubt for a moment you are getting the results you say but I'm
baffled. If we consider how the formula works with a slightly modified
version for clarity

=SUMPRODUCT(--(Products!$C$2:$C$10=C57)/(COUNTIF(Products!$G$2:$G$10,Products!$G$2:$G$10&" ")))


if c2 - c10 are all the same as c57 then this bit returns an array of 1s

this bit

(--(Products!$C$2:$C$10=C57)

returns

SUMPRODUCT({1;1;1;1;1;1;1;1;1}

if in the next column we have 5 number 1 and 4 number 2, this bit
COUNTIF(Products!$G$2:$G$10,Products!$G$2:$G$10&"" )

returns
{5;5;5;5;5;4;4;4;4})

if we then product those 2 arrays we get

.2;.2;.2;.2;.2;,25;.25;.25;.25

if we then sum this array we get 2 for the 2 unique values so again i'm
baffled how this returns a decimal and hope someone can rescue us (me)

Try this array formula** :

=COUNT(1/FREQUENCY(IF(Sheet2!$C$2:$C$1000=C57,Sheet2!$G$2:$ G$1000),Sheet2!$G$2:$G$1000))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT
key then hit ENTER.

The problem with this formula:


If the same number is associated with more than 1 name then you get
incorrect results.

C57 = Tom

Tom...40
Tracy ...40

Thanks for pointing that out, it is about the only thing I never tried to
make the formula error out but as soon as you have the reason for the
decimals is obvious.

Hi,

You can also try this. This is a non-array formula solution

1. Assume that in sheet 2, you have data in E5:F9 as follows:

Name Number
Ashish 12
Mahesh 23
Ashish 34
Mahesh 12
Rajesh 12

2. In B33, enter data as follows Name, Occurrence, Count unique
3. In B4:B6, enter Ashish, Mahesh, Rajesh
4. In C4, enter =COUNTIF(Sheet2!$G$6:$G$10,Sheet2!G$6) and copy down till C6
5. In cell D4, enter
=DCOUNT(Sheet2!$C$5:$G$10,Sheet2!G$5,Sheet1!$B$3:C 4)-SUM($D$3:$D3) and copy
down till D6

Please note that this formula will work only when the col. G entries in
sheet 1 are all numbers.

Hope this helps.
