How do I find the Excel column name that corresponds to a given integer? [duplicate]

Answer 1

This works fine in MS Excel 2003-2010. Should work for previous versions supporting the Cells(...).Address function:

1. For the 28th column - taking columnNumber=28; Cells(1, columnNumber).Address returns "$AB$1".
2. Doing a split on the $ sign returns the array: ["","AB","1"]
3. So Split(Cells(1, columnNumber).Address, "$")(1) gives you the column name "AB".

Taken from How to convert Excel column numbers into alphabetical characters

' The following VBA function is just one way to convert column number 
' values into their equivalent alphabetical characters:

Function ConvertToLetter(iCol As Integer) As String
   Dim iAlpha As Integer
   Dim iRemainder As Integer
   iAlpha = Int(iCol / 27)
   iRemainder = iCol - (iAlpha * 26)
   If iAlpha > 0 Then
      ConvertToLetter = Chr(iAlpha + 64)
   End If
   If iRemainder > 0 Then
      ConvertToLetter = ConvertToLetter & Chr(iRemainder + 64)
   End If
End Function
