Excel VBA Loop on columns

If you want to stick with the same sort of loop then this will work:

Option Explicit

Sub selectColumns()

Dim topSelection As Integer
Dim endSelection As Integer
topSelection = 2
endSelection = 10

Dim columnSelected As Integer
columnSelected = 1
Do
   With Excel.ThisWorkbook.ActiveSheet
        .Range(.Cells(columnSelected, columnSelected), .Cells(endSelection, columnSelected)).Select
   End With
   columnSelected = columnSelected + 1
Loop Until columnSelected > 10

End Sub

EDIT

If in reality you just want to loop through every cell in an area of the spreadsheet then use something like this:

Sub loopThroughCells()

'=============
'this is the starting point
Dim rwMin As Integer
Dim colMin As Integer
rwMin = 2
colMin = 2
'=============

'=============
'this is the ending point
Dim rwMax As Integer
Dim colMax As Integer
rwMax = 10
colMax = 5
'=============

'=============
'iterator
Dim rwIndex As Integer
Dim colIndex As Integer
'=============

For rwIndex = rwMin To rwMax
        For colIndex = colMin To colMax
            Cells(rwIndex, colIndex).Select
        Next colIndex
Next rwIndex

End Sub

Yes, let's use Select as an example

sample code: Columns("A").select

How to loop through Columns:

Method 1: (You can use index to replace the Excel Address)

For i = 1 to 100
    Columns(i).Select
next i

Method 2: (Using the address)

For i = 1 To 100
 Columns(Columns(i).Address).Select
Next i

EDIT: Strip the Column for OP

columnString = Replace(Split(Columns(27).Address, ":")(0), "$", "")

e.g. you want to get the 27th Column --> AA, you can get it this way

Another method to try out. Also select could be replaced when you set the initial column into a Range object. Performance wise it helps.

Dim rng as Range

Set rng = WorkSheets(1).Range("A1") '-- you may change the sheet name according to yours.

'-- here is your loop
i = 1
Do
   '-- do something: e.g. show the address of the column that you are currently in
   Msgbox rng.offset(0,i).Address 
   i = i + 1
Loop Until i > 10

** Two methods to get the column name using column number**

• Split()

code

colName = Split(Range.Offset(0,i).Address, "$")(1)

• String manipulation:

code

Function myColName(colNum as Long) as String
    myColName = Left(Range(0, colNum).Address(False, False), _ 
    1 - (colNum > 10)) 
End Function
