Very nice - I don't think I've come across this project before.

I'm curious, what's your vision for react-spreadsheet? I notice it supports some formulas, and a "single sheet" view. Do you plan to make it a more complete spreadsheet component in future, or do you see that as out of scope?

Thank you! The vision is to support as many spreadsheet capabilities as possible while retaining the simplest API and a small enough size. So multi-sheet is possible as long as using the component with a single sheet is still simple.
