Use the Name Manager dialog box to work with all of the defined names and table names in the workbook. For example, you may want to find names with errors, confirm the value and reference of a name, view or edit descriptive comments, or determine the scope. You can also sort and filter the list of names, and easily add, change, or delete names from one location.
To open the Name Manager dialog box, on the Formula tab, in the Defined Names group, click Name Manager
