Show HN: OpenSheet – experimenting with how LLMs should work with spreadsheets

Hi folks. I've been doing some experiments on how LLMs could get more handy in the day to day of working with files (CSV, Parquet, etc). Earlier last year, I built https://datakit.page and evolved it over and over into an all in-browser experience with help of duckdb-wasm. Got loads of feedbacks and I think it turned into a good shape with being an adhoc local data studio, but I kept hearing two main things/issues:

Why can't the AI also change cells in the file we give to it?

Why can't we modify this grid ourselves?

So besides the whole READ and text-to-SQL flows, what seemed to be really missing was giving the user a nice and easy way to ask AI to change the file without much hassle which seems to be a pretty good use case for LLMs.

DataKit fundamentally wasn't supposed to solve that and I want to keep its positioning as it is. So here we go. I want to see how https://opensheet.app can solve this.

This is the very first iteration and I'd really love to see your thoughts and feedback on it. If you open the app, you can open up the sample files and just write down what you want with that file.
