For some value of web developer, probably. Although I think you are overestimating the complexity of Excel for pivot tables for the average non-computer person.

For some value of web developer, probably. Although I think you are overestimating the complexity of Excel for pivot tables for the average non-computer person. Still the level of web-developer who has little more skill than using Excel for pivot tables is also the web developer who can do little more than make static websites, which is plenty enough to be a webdev in 95 or even in 2005, but unlikely to be enough in 2017. I have just made different orders from two different websites today (cables and clothing) and both websites made decent usage of javascript, search, etc. Besides that, many factories had thousands of employees; even a modest store may have ten - but watchapp needed just 50 programmers to be sold for a double digit billion dollar sum.
