There is probably not much you could check. You could probably do some type checking but beyond that I see - ad hoc - not much one could do. Excel does already catch syntax errors and a few other errors mentioned in the link. Maybe you could make these errors more prominent. But should we really encourage more development using office software? Shouldn't we solve the actual problem?
