Excel file access password

J

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?

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........
