I have a question about calculator building, if anyone has a suggestion. My industry revolves around quite complicated calculators, with anywhere from 10 to 50 data inputs - and the result are large projection tables and charts.

These still live in excel, but I would love to move then into a web app.

Is there a best practice way to go about this? I've tried basic html forms that pass to python for the number crunching (there are optimisations and Monte Carlos). But it gets so messy as the number of input fields increase. Does a tool exist to simplify this process?
