While I see the point the Ulaş is getting at, I wouldn't call this JSON-driven development. I think JSON-driven development would use abstraction layers that are based on JSON, like JSON schema, and perhaps an OOP library that leverages it. What I'd actually call this problem is a lack of abstraction. In functional programming, simple data structures are often preferred, and composable functions are used to manage complexity. A functional programmer might declare a function `to_structured_dict(enumerable, path)` and call it with `to_structured_dict(book_list, path=('shop_label', 'cell_label, 'book_id', count'))`
