Count unique values in Excel

Question

I need to count unique values in range (C2:C2080) in excel. Googled formula:

=SUM(IF(FREQUENCY(MATCH(C2:C2080;C2:C2080;0);MATCH(C2:C280;C2:C2080;0))>0;1))         


        

Answer 1

Here is a VBA function that works for me.

You can use it as a worksheet function, referencing any range, eg “=CountUnique(N8:O9)”

It handles text and numeric values, and treats blank cells as one value

It does not require dealing with array functions.

It requires a reference to the Microsoft Scripting Library, for the dictionary object.

    Public Function CountUnique(rng As Range) As Integer
        Dim dict As Dictionary
        Dim cell As Range
        Set dict = New Dictionary
        For Each cell In rng.Cells
             If Not dict.Exists(cell.Value) Then
                dict.Add cell.Value, 0
            End If
        Next
        CountUnique = dict.Count
    End Function
