Economic Models in Excel? Or online? Change variables, see effect. Solve for max/min. Revise model.

I did a dual-major in university, half in economics, 20 years ago.  I thought by now I would be able to find an online economics course with functioning economic models.   Nope.  Am I just looking in the wrong places?  I found online courses with static diagrams, but not functioning models.

Bonus #1: users can change the labels and the data.

Bonus #2: users can revise the model itself.  Do you know of any spreadsheet-based or online models that allow users to not just change variables but to edit the model itself?

Hessian Matrices, Lagrangian Multipliers, Local and Global Maxima and Minima, Saddle Points, Higher Order Derivatives ---- these are what my dreams are made of!

(And: indifference curves, aggregate demand, socially-optimal vs privately-optimal output, Edgeworth box...)

Most economic and econometric models are written in languages like Stata, R, Python, or Matlab. For example, many central banks provide data and code in Matlab format. Many applied microeconomics papers provide data and code in Stata format.
