I've built an excel workbook and I have someone that would like to
look at it. Can I provide them a copy with a macro of some kind that
would require a password to open at 10 days or a period I specify? Can
it include a message that the trial period is over?

Is that possible? I know that passwords can be cracked, but I don't
think there is much of a threat from my potential clients.

Is there a way to conditionally format the pertinent cells (10 cells
+/-) on a page to fill black and become useless after a 10 day
period?
