It's not quite clear what you mean by "rules"; but in general the answers
probably boil down to possible - yes, easy - no.

If you want to build a set of constraints for a fixed class of problems
(for instance, mixed integer programming) in Excel and then solve it with
ECLiPSe, that should be no problem.  Just export your constraints in a
file format that's as easy to read as possible, and then write ECLiPSe
code to read the file and turn it into constraints.

However, if your idea of "rules" includes creating new user-defined
constraints and other higher-complexity logic programming tasks, I'm
finding it hard to imagine how expressing those in a spreadsheet and then
translating to ECLiPSe could possibly be easier than just having your
users learn the language.  Logic programming in general is not
"business-user-friendly" if by that you mean "accessible to persons
without the necessary technical skills"; and anyone who CAN learn logic
programming will find it easier to operate without the handicap of a
spreadsheet intermediate layer.
