a twist on counting unique values in a range which contains blankcells, using a formula. the formula can't use SUMPRODUCT or FREQUENCY
 

I need a formula, not VB code, to count the number of unique values in a column of up to 10,000 rows, some of which will be blank. The values may be numeric, alphanumberic, or text.

The twist is that the formula can't use either the SUMPRODUCT or the FREQUENCY functions. The excel handler which processes the file for a database can't handle SUMPRODUCT or FREQUENCY.

I got very close with this array formula: =SUM(1/COUNTIF(A1:A36,A22:A36)) But as you can see it has to be limited to the range of nonblank cells, since it throws a #DIV/0 error if the range includes blank cells.

I've made some unsuccessful attempts at using COUNTIFS with criteria for only nonblank cells.

Any ideas?

Thanks in advance!

hi,

=COUNTIF(A1:A65535,A1:A65535)-1

try:
=SUM(IF(A1:A36<"",1/COUNTIF(A1:A36,A1:A36)))
and insert the formula with CTRL+Shift+Enter

if you have a lot of rows the array formula is very slow.
Try this UDF:

Function UniqueVals(myRng As Range) As Long
Dim myDic As Object
Dim varTmp As Variant, varData As Variant
Dim i As Long, Counter As Long

Set myDic = CreateObject("Scripting.Dictionary")
varTmp = myRng
For i = LBound(varTmp) To UBound(varTmp)
myDic(varTmp(i, 1)) = varTmp(i, 1)
Next
varData = myDic.items
For i = LBound(varData) To UBound(varData)
If varData(i) < "" Then Counter = Counter + 1
Next
UniqueVals = Counter
End Function

Call it in the worksheet with
=UniqueVals(A1:A10000)
