Create excel ranges using column numbers in vba?

Question

How is it possible to create a range in vba using the column number, rather than letter?

Answer 1

Range.EntireColumn

Yes! You can use Range.EntireColumn MSDN

dim column : column = 4

dim column_range : set column_range = Sheets(1).Cells(column).EntireColumn

Range("ColumnName:ColumnName")

If you were after a specific column, you could create a hard coded column range with the syntax e.g. Range("D:D").

However, I'd use entire column as it provides more flexibility to change that column at a later time.

Worksheet.Columns

Worksheet.Columns provides Range access to a column within a worksheet. MSDN

If you would like access to the first column of the first sheet. You would call the Columns function on the worksheet.

dim column_range: set column_range = Sheets(1).Columns(1)

The Columns property is also available on any Range MSDN

EntireRow can also be useful if you have a range for a single cell but would like to reach other cells on the row, akin to a LOOKUP

dim id : id = 12345


dim found : set found = Range("A:A").Find(id)

if not found is Nothing then
    'Get the fourth cell from the match
    MsgBox found.EntireRow.Cells(4)
end if
