Excel spreadsheet to Crystal Report?

does it make sense to try to "convert" an Excel spreadsheet with tons of formulas to a Crystal Report?
I'm having a hell of a time trying to get it working due to the way things are calculated in Crystal like you can't just direct a cloumn of data to divide but a number in a "cell" the running total is killing me.

any ideas?
is this even feasible? should I tell the client to find alternatives?

thanksam I clear in my question?
can anyone comment?
