Function to convert column number to letter?

Question

Does anyone have an Excel VBA function which can return the column letter(s) from a number?

For example, entering 100 should return CV.

Answer 1

And a solution using recursion:

Function ColumnNumberToLetter(iCol As Long) As String

    Dim lAlpha As Long
    Dim lRemainder As Long

    If iCol <= 26 Then
        ColumnNumberToLetter = Chr(iCol + 64)
    Else
        lRemainder = iCol Mod 26
        lAlpha = Int(iCol / 26)
        If lRemainder = 0 Then
            lRemainder = 26
            lAlpha = lAlpha - 1
        End If
        ColumnNumberToLetter = ColumnNumberToLetter(lAlpha) & Chr(lRemainder + 64)
    End If

End Function
