How to: Refer to Sheets by Index Number
Published: July 16, 2012
An index number is a sequential number assigned to a sheet, based on the position of its sheet tab (counting from the left) among sheets of the same type. The following procedure uses the Worksheets property to activate the first worksheet in the active workbook.
Sub FirstOne() Worksheets(1).Activate End Sub
If you want to work with all types of sheets (worksheets, charts, modules, and dialog sheets), use the Sheets property. The following procedure activates sheet four in the workbook.
Sub FourthOne() Sheets(4).Activate End Sub
The index order can change if you move, add, or delete sheets.
