Gridlines help give you visual cues when you're formatting in Office. You can align shapes and other objects in your PowerPoint slides and Word documents, and distinguish between cell boundaries in and sections of your spreadsheets and workbooks in Excel.

In Word and PowerPoint, gridlines are for visual reference only and cannot be printed. If you want to print gridlines in Excel, see Print gridlines in a worksheet.
To show the gridlines, in Excel, PowerPoint, or Word, click the View tab, and then check the Gridlines box.
To hide the gridlines, clear the Gridlines check box.
