Working in Microsoft Excel 2013 without gridlines can make sense for some projects. However, if someone sent you a file and you need gridlines to make sense of everything, you can re-enable gridlines through the Ribbon toolbar. Alternatively, if the file you look at on your computer has gridlines and the printed file doesn't, you'll need to re-enable the ability to print the file with gridlines through the Page Layout menu on the Ribbon toolbar.
Click to select the workbook you want to display gridlines within in the lower left corner of the screen. Alternatively, if you want to activate gridlines in multiple workbooks, hold down the "Shift" button and select the workbooks in which you want to display gridlines.
