As Dave said, you can't "really" make Excel so secure that at competent
person cannot get in, but you "can" make the trip in so confounding that
only a truely dedicated individual will go through all the necessaries to get
there.........thereby, "keeping the honest people out"....
You could incorporate things like: 1-workbook won't open unless macros are
enabled, 2- Pass word(s) are invoked, 3-Only users with name on a list can
access, 4- only user putting secret value into specific cell can gain access,
etc etc........

I have excel files that I am selling to clients. I have seen other excel
templates that have features that I need such as: 1) You cannot copy the text
from the screen 2) You need a password to access similar to registration of
new software 3) Allows a 30 day free access then it become unavailable. Does
excel itself have these features or do I need to buy some other software?
