Hi there, I tried to build a CLI tool to edit and visualize Excel/CSV files directly in the terminal, I called it "dss".

I did it for fun to tweak spreadsheet formulas without leaving my terminal or opening heavy GUI apps.

It is an interactive editor of sheets with charts and formula engine diretly in TUI. The formula engine is handmaded but I'd like to improve it.

I copied a lot from my previous Datacmd project and from Termdash repo. Hoping to receive some feedback.
