Excel VBA Remove Triple Duplicate in One Row Loop - vba

Question

I want to delete entire row when all 3 numeric values in cells in columns G,H,I are equal. I wrote a vba code and it does not delete nothing. can Someone advise?
Sub remove_dup()
Dim rng As Range
Dim NumRows As Long
Dim i As Long
Set rng = Range("G2", Range("G2").End(xlDown))
NumRows = Range("G2", Range("G2").End(xlDown)).Rows.Count
For i = 2 To NumRows
Cells(i, 7).Select
If Cells(i, 7).Value = Cells(i, 8).Value = Cells(i, 9).Value Then
EntireRow.Delete
Else
Selection.Offset(1, 0).Select
End If
Next i
End Sub

Answer 1

Try this code. When deleting rows, always start from last row and work towards first one. That way you are sure you wont skip any row.
Sub remove_dup()
Dim rng As Range
Dim NumRows As Long
Dim i As Long
NumRows = Range("G2", Range("G2").End(xlDown)).Rows.Count
For i = NumRows + 1 To 2 Step -1
If Cells(i, 7).Value = Cells(i, 8).Value And Cells(i, 7).Value = Cells(i, 9).Value Then
Cells(i, 7).EntireRow.Delete
Else
End If
Next i
End Sub

Remember when you delete rows, all you need to loop in reverse order.
Please give this a try...
Sub remove_dup()
Dim NumRows As Long
Dim i As Long
NumRows = Cells(Rows.Count, "G").End(xlUp).Row
For i = NumRows To 2 Step -1
If Application.CountIf(Range(Cells(i, 7), Cells(i, 9)), Cells(i, 7)) = 3 Then
Rows(i).Delete
End If
Next i
End Sub

You can delete all rows together using UNION. Try this
Sub remove_dup()
Dim ws As Worksheet
Dim lastRow As Long, i As Long
Dim cel As Range, rng As Range
Set ws = ThisWorkbook.Sheets("Sheet4") 'change Sheet3 to your data range
With ws
lastRow = .Cells(.Rows.Count, "G").End(xlUp).Row 'last row with data in Column G
For i = lastRow To 2 Step -1 'loop from bottom to top
If .Range("G" & i).Value = .Range("H" & i).Value And .Range("G" & i).Value = .Range("I" & i).Value Then
If rng Is Nothing Then 'put cell in a range
Set rng = .Range("G" & i)
Else
Set rng = Union(rng, .Range("G" & i))
End If
End If
Next i
End With
rng.EntireRow.Delete 'delete all rows together
End Sub
