Custom, user-defined names are identifiers that represent information in the sheet. A custom name can refer to a range of cells or a formula. You can define a custom name and then use the name in formulas. When the formula is evaluated, the custom name's value is referenced and evaluated. Use the SetCustomName method to create a custom name.
The following example creates custom names and uses them in formulas.
