In my experience, it's actually quite hard to move a business from an excel sheet to software. Because an excel sheet allows the end user to easily handle every edge case and they likely don't even think in terms of "edge cases"

Whilst you could plausibly argue that Microsoft have spent the past 25 years attempting to stamp them out, this is exactly what VB6 and VBA were.
People built whole businesses on/around these technologies, and people liked them because you could get something working fast. As maligned as they are nowadays they were so widely used because they delivered value.
