Hi everyone, wonder if anyone can help me with this problem.

I have spredsheets ready which took alot of work to build. I do these
spreadsheets to ease the work load from the office I work at, but I do not
like the fact that this work can easily be copied and anyone can use these
spreadsheets without my permission. Is it possible to protect these
spreadsheets from being copied? Thank you in anticipation.
