What does the Name Box display in Excel?

The Name Box in Excel serves a specific function by displaying the location of the active cell. Whenever you click on a specific cell, the Name Box updates to show the coordinates of that cell, formatted as the column letter followed by the row number (for example, "A1" for the first cell in the top left corner). This feature is particularly helpful for users as it provides a quick reference to which cell is currently selected, making navigation and formula creation easier.

In contrast, the other options represent functions or features that are not related to the Name Box. For example, the sum of cell data would typically be found in the formula bar or as a result of a formula entered within a cell, rather than in the Name Box itself. The user's name might be displayed in the application title or settings, but not in the Name Box. Finally, the number of worksheets in a workbook is visible in the tabs at the bottom of the Excel window, not in the Name Box. Therefore, recognizing that the Name Box's primary purpose is to indicate the active cell's location clarifies why this option is correct.
