Unlike Access, Excel does not have an auto-numbering feature that increments a number each time you add a new row. With Excel 2003 and 2007, you can use the Row function to add your own auto-numbering to a data list.
For example, say you are creating a list of all of your company’s products and their prices. Follow these steps to add your own autonumbering for the list:
Now when you type the name of the next product in B3 and press [Tab], Excel will automatically fill in the next number for you.
