This is something I built a little while ago. It's a proof-of-concept and inspired by what I was doing in my day job.

To play with the demo spreadsheet you'll need to clone the repo and run the demo script, ie:

  git clone git@github.com:bsdz/calcengine.git
  cd calcengine
  python3 -mvenv --prompt calceng .venv
  . ./.venv/bin/activate
  poetry install -E demo
  python demo/spreadsheet/main.py

There's an inline gif showing the spreadsheet in use.

Hope it's interesting :)
