I'm sorry it was hard to follow. The Excel sheets I've seen have been hard to follow, too! Also, most of the work is not actually VBA (there's a little), but formulas in spreadsheet cells. The key difference is that the Excel spreadsheet is not a prototype: It's an MVP, which includes "viable"; many businesses have been making money with them for years. Another key feature of the 'prototype' is that the team is able to edit the Excel formulas, but burying the formulas as JS or Python (whether locked away serverside or simply obfuscated by nature of being different language with a new learning curve) removes a critical feature.
