Banker (banker.so): An AI spreadsheet that excels at spreadsheet understanding (pun intended).

There are some AI spreadsheet products out there mostly as plugins along with MS Copilot. However my experience with them showed that they are bad at understanding spreadsheets.

The reason is that sheets are 2D data models. Because LLMs are trained on 1D data models (simply text), translation of 2D data models to formats an LLM can consume is a big context engineering task.

I read and implemented some of the algos mentioned in SpreadsheetLLM paper released by Microsoft. Ironic, isn't it?

Got it to a nice working state. Give it a go - if you need more tokens, let me know!
