Protecting the Worksheet and the Workbook
Once you’ve put all that work into your workbook, having outfitted it with rows of
complex formulas and breathtaking charts, you may get a bit nervous about what might
happen next. What if you were to accidentally overwrite—or delete—a formula? True,
you might be able to bring it back with an Undo command, but that prospect would
depend on exactly when you discovered the mishap. Worse yet, what if your five-year-
old nephew began to type some formulas of his own on the sheet?
Have no fear. Excel has anticipated those calamities, by allowing you to protect your
workbooks and individual worksheets with a set of options that should help you fend off
little Timmy’s editorial changes and leave your masterpiece intact.
By way of introduction, you need to understand what protecting a sheet does and
doesn’t do. Protecting a sheet won’t seal off your sheet with industrial-strength
invincibility, foiling the bad guys who want to compromise or steal your data. Not quite,
because workbook and worksheet protection is more about warding off mistakes than
disarming hackers who have your formulas in their sights. Still, protection can do a
pretty good job of, well, protecting your work.
The process of protecting worksheets and workbooks is actually quite easy, but the
details get a bit quirky, as you’ll see.
