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

Another way to do this is this:

Sub CountUnique()
    Dim Count, x, a, lastRow, Values(), StringValues
    a = ActiveCell.Column
    a = GetLetterFromNumber(a)
    lastRow = Range(a & Rows.Count).End(xlUp).row
    Count = 0
    For Each c In Range(Range(a & "1"), Range(a & Rows.Count).End(xlUp))
        If c.row = 1 Then
            ReDim Values(lastRow)
            Values(Count) = c.Value
            Count = Count + 1
        End If
        StringValues = Join(Values, "#")
        StringValues = "#" + StringValues
        If InStr(1, StringValues, c.Value) = 0 Then
            Values(Count) = c.Value
            Count = Count + 1
        End If
    Next c
    MsgBox "There are " & Count & " unique values in column " & a
End Sub

You just have to have the active cell be on row 1 of the column that you are counting.
