Worksheet.Columns Property (Excel)
Returns a Range object that represents all the columns on the active worksheet. If the active document isn't a worksheet, the Columns property fails.
Syntax
expression .Columns
expression A variable that represents a Worksheet object.
Remarks
Using this property without an object qualifier is equivalent to using ActiveSheet.Columns.
When applied to a Range object that's a multiple-area selection, this property returns columns from only the first area of the range. For example, if the Range object has two areas — A1:B2 and C3:D4 — Selection.Columns.Count returns 2, not 4. To use this property on a range that may contain a multiple-area selection, test Areas.Count to determine whether the range contains more than one area. If it does, loop over each area in the range.
Example
This example formats the font of column one (column A) on Sheet1 as bold.
Worksheets("Sheet1").Columns(1).Font.Bold = True
