Excel VBA Loop on columns

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
