As has been suggested, you can select all the sheets, and format them.

WARNING -- While the sheets are grouped, any changes you make to one
sheet will be applied to all the other sheets that are selected.

To select all the sheets quickly:
Right-click on any sheet tab
Choose Select All Sheets

Then choose FilePage Setup
Format the sheets, and click OK

When finished, ungroup the sheets, to prevent damage to the data:
Right-click on any sheet tab
Choose Ungroup Sheets
