Locked cells

[Boots]

Is there any simple way of identifying all locked cells on a sheet?

 

[Dave Peterson]

Are you using Format|Conditional Formatting for anything?

If no, then how about using it to show the locked/unlocked cells?

Select your range (ctrl-A for all the cells).
Format|Conditional formatting
formula is: =CELL("protect",A1)

(Use the activecell's address instead of A1.)
