Back at a job I had in ~2008 we built a library to convert an Excel spreadsheet into a fully functional web based configurator. I've talked about it here previously[1].

I have always thought that it was a missed opportunity that we'd never reused it nor turned it into any sort of SaaS. It seems to me like such an obvious and easy way to let your clients define their own business logic without having to maintain it yourself.
