Getting Headers or Footers

Headers and footers are displayed only in Page Layout view, Print Preview, and on printed pages.

You can also use the Page Setup dialog box if you want to view headers or footers for more than one worksheet at a time.

For other sheet types, such as chart sheets, or charts, you can insert headers and footers only by using the Page Setup dialog box.
