Defined names

A defined name is a user-defined label or identifier representing a specific cell, range of cells, formula, or constant value. A defined name can be used in place of a cell or range reference in a formula, making it easier to read and understand. For example, you might define Sales, which refers to the range of cells containing your sales data. Then, instead of referring to those cells as A1:A10 in a formula, you can use the name Sales instead.

Enterprise feature
This feature is only available with the premium extension for formulas.
