VLookup function range in Excel using macro

Question

I am trying to make a macro to do the vlookup in excel. I have succeed to create and the code is working fine! The code as below:

ActiveCell.FormulaR1C1 = _ "=VLOOKUP(RC[-1],LW0640!R2C8:R12163C9,2,TRUE)" Selection.AutoFill Destination:=Range("D6:D6098")

However, I found that the range is fix range. which is from D6:D6098 on the result and R2C8:R12163C9 from the source.

And it will not work if the data range changes. I want to know how to make the range for the vlookup function from the beginning until the last row in the range. Please help!

Answer 1

You can use the "A1" type of notation. In your case, you want column 8 and 9, which are respectively H and I, so you can write the following:

ActiveCell.FormulaR1C1 = _
"=VLOOKUP(RC[-1],LW0640!H:I" & MyCols & ",2,TRUE)"
Selection.AutoFill Destination:=Range("D6:D6098")

Answer 2

You can use this code.

Sheets("LW0640").Select
Range("D6:D6098").Select
    ActiveWorkbook.Names.Add Name:="tablex", RefersToR1C1:= _
        "=LW0640!R6C4:R6098C4"


'Range("F28").Select
ActiveCell.FormulaR1C1 = "=VLOOKUP(RC[-1],tablex,2,TRUE)"

Answer 3

Try

Sub Demo()
    Dim ws As Worksheet
    Dim LastRow As Long

    Set ws = ThisWorkbook.Sheets("Sheet1")  'change Sheet1 to your data sheet
    With ws
        LastRow = .Range("H" & .Rows.Count).End(xlUp).Row
        .Range("D6:D" & LastRow).Formula = "=VLOOKUP(C6,LW0640!$H$2:$I$" & LastRow & ",2,TRUE)"
    End With
End Sub

You should avoid using SELECT and ACTIVE . See this for details.
