Hello everyone,

I am attempting to remove duplicates in three columns individually. The data is a trial balance on a sheet entitled TB. I am selecting columns A, B, and C and copying those columns to a new sheet called Criteria. Once I get the columns to Criteria, I need to remove the duplicates in each column individually. It works except for the last column. My trial balance is about 500 rows so for my example shown here I will display only a few rows. My code is as follows:

Sub Macro1()
'
' Macro1 Macro
'
' Keyboard Shortcut: Ctrl+z
'
Sheets("Sheet1").Select
Sheets("Sheet1").Copy Before:=Sheets(1)
Sheets("Sheet1 (2)").Select
Sheets("Sheet1 (2)").Name = "Criteria"
Application.GoTo ActiveWorkbook.Sheets("TB").Cells(1, 1)
ActiveSheet.Range("a1", ActiveSheet.Range("a1").End(xlDown)).Select
Selection.Copy
Application.GoTo ActiveWorkbook.Sheets("Criteria").Cells(1, 1)
ActiveSheet.Paste
Application.CutCopyMode = False
Application.GoTo ActiveWorkbook.Sheets("Criteria").Cells(1, 1)
OnlyColumnA
Application.GoTo ActiveWorkbook.Sheets("TB").Cells(1, 2)
ActiveSheet.Range("b1", ActiveSheet.Range("b1").End(xlDown)).Select
Selection.Copy
Application.GoTo ActiveWorkbook.Sheets("Criteria").Cells(1, 2)
ActiveSheet.Paste
Application.CutCopyMode = False
Application.GoTo ActiveWorkbook.Sheets("Criteria").Cells(1, 2)
OnlyColumnB
Application.GoTo ActiveWorkbook.Sheets("TB").Cells(1, 3)
ActiveSheet.Range("c1", ActiveSheet.Range("c1").End(xlDown)).Select
Selection.Copy
Application.GoTo ActiveWorkbook.Sheets("Criteria").Cells(1, 3)
ActiveSheet.Paste
Application.CutCopyMode = False
Application.GoTo ActiveWorkbook.Sheets("Criteria").Cells(1, 3)
OnlyColumnC
End Sub
Sub OnlyColumnA()
Dim n As Long

n = Cells(Rows.Count, "A").End(xlUp).Row
ActiveSheet.Range("A1:A" & n).RemoveDuplicates Columns:=1, Header:=xlYes
End Sub
Sub OnlyColumnB()
Dim m As Long

m = Cells(Rows.Count, "B").End(xlUp).Row
ActiveSheet.Range("B1:B" & m).RemoveDuplicates Columns:=1, Header:=xlYes
End Sub
Sub OnlyColumnC()
Dim p As Long

p = Cells(Rows.Count, "C").End(xlUp).Row
ActiveSheet.Range("C1:C" & p).RemoveDuplicates Columns:=1, Header:=xlYes
End Sub

When I run this, I still have duplicates in column C. The data I am using is of this nature:

Try this :-
From sheets "TB" to "Criteria"
Code: 
[COLOR="Navy"]Sub[/COLOR] MG06Jun22
[COLOR="Navy"]Dim[/COLOR] Ray [COLOR="Navy"]As[/COLOR] Variant, n [COLOR="Navy"]As[/COLOR] [COLOR="Navy"]Long,[/COLOR] Dic [COLOR="Navy"]As[/COLOR] Object
Ray = Sheets("Tb").Cells(1).CurrentRegion
[COLOR="Navy"]Set[/COLOR] Dic = CreateObject("scripting.dictionary")
Dic.CompareMode = vbTextCompare
ReDim nRay(1 To UBound(Ray, 1), 1 To 3)
[COLOR="Navy"]For[/COLOR] ac = 1 To 3
    [COLOR="Navy"]For[/COLOR] n = 1 To UBound(Ray, 1)
        Dic(Ray(n, ac)) = Empty
    [COLOR="Navy"]Next[/COLOR]
        [COLOR="Navy"]With[/COLOR] Sheets("Criteria").Cells(1, ac).Resize(Dic.Count)
            .Value = Application.Transpose(Dic.keys)
            .Parent.Range("C:C").NumberFormat = "@"
        [COLOR="Navy"]End[/COLOR] With
        Dic.RemoveAll
