Awesome feedback twobitshifter, adding industrial use cases is on my task list now. One use case is to convert the insurance premium calculation logic defined in Excel into APIs and to be consumed by web/mobile apps to sell to end customers. In general, the people in the company who uses Excel most likely don't have software development skills, and the software developers are less likely to have time to fully understand the business logic in order to translate them accurately into code. That's how a product like SheetHub can bridge the gap, separate the responsibilities, and enables more rapid iterations on both sides. The audiences I was aiming for initially are developers like myself, that's why the languages are more technical. But you're right, I indeed need to broader the audience.
