And I absolutely agree. My point was that Excel workbooks exist in a no man's land, where untenable practices are allowed by necessity. When we transition away inevitably we add layers of error checking and validations and security controls and processes, etc, that turn a simple project into a monstrosity. But it isn't that Excel was efficient anymore than having the random cowboy coder throw together the most adhoc thing imaginable (but quickly) is efficient.
