I always like these threads where programmers talk about tools like Excel and say they’re fine for small stuff but grow out of hand, as if 90% of codebases built by professional programmers aren’t exactly the same.
But professional programmers (emphasis on professional) are well aware of how codebases can grow out of hand and employ entire categories of theories, strategies and tools to keep their software maintainable, even when under delivery/time pressure. Excel doesn't really have much in this category of theories and tools.
