I was thinking of adding a simple calculator to one wiki I am at. I have a JSON file with data that I want to use and fill a combobox with part of this data too. Is it possible to do this without any extension and/or Javascript? Or I'm required to use both in order to achieve this?

Thanks!

You need to use both. However, I'm not sure what's the purpose of a JSON file for a calculator.

Because I need to use specific data and apply that data to the formulas I have.

Have you tried using a Spreadsheet instead of a wiki? Look at open office/Libre office/Microsoft excel
