Maintainability » everything else.

Basically on the long term the possibility to use real code that is easy to change and understand will save you incredible amounts of time. If you reach a point where your code is too complicated that you are afraid to change anything, you're basically stuck.

I guess it depends on what you mean by worse. In my case, I abandoned excel and rebuilt the tool as a web app using Vue.js, Chart.js, Firebase, etc., which is what ProjectionLab is now. More overall development work, but the end result is way better than a spreadsheet.

But would you say using that web stack initially would have been overkill?
