Comments in Excel 2013 can help annotate parts of a spreadsheet where comments wouldn't fit, such as within a table. Even though comments don't directly display on the spreadsheet, you can print them on paper with your content. It is possible to print a comment in its original location or as a group at the end of the spreadsheet.
Hover over any cell marked by a color in the upper right corner. This dogeared cell has a comment attached to it; displaying it reveals a box with an arrow pointing toward the cell. Inside the box is a comment and the name of the user who typed it.
Click the "Review" tab in the upper toolbar. Selecting "Show All Comments" reveals any comments on the worksheet, even when you don't hover the mouse over the cell. At this point, however, printing the document still won't show the comments.

Switch to the "Page Layout" tab and click the arrow in the lower right corner of Page Setup to open a box with more advanced options, including "Comments" in the Print category. By default, this is set to "None," meaning comments don't print even when shown onscreen.
Select "As displayed on sheet" to print the document as you see it on the paper. Alternatively, choose "At end of sheet" to display comments in a plain text list following your spreadsheet's content. Click "OK" to save your changes or "Print" to begin printing.
