A bit of a duplicate comment that my response to melchebo above: looking at it quickly, it looks like it addresses a different problem. PowerApps seems to be directed at giving business users the ability to quickly create a simple CRUD application &#x2F; website. But I think the use case where the business logic has to sit in Excel and be owned by the business is where you have a complex logic in Excel, like a tax calculation, or a regulatory formula, or some complex quote for a client, etc. They are problems that are intrinsically complex and that IT can&#x27;t really productionise by just looking at a couple of formulas, and where having the ability to express the logic in Excel but use it on a server has value.
