fighting excel in headless runs using COM. fighting AG grid building excel apps, blowing out tons of js trying to match excel dashboards. drift between dashboard and app, endless. users accidentally over writing excel models. no version control.
decided to just re-write excel. ended up being a little bit of github for excel, faster excel using Polars lazyframe, AG grid but embedded spreadsheet (so it's the same thing the user builds), and native versioning.
ai is integrated to write plugin code, not be "copilot". code is also versioned.
just a bunch of stuff i run into coding on trading desks, tried to solve it. open source.
