EINFACH · SPREADSHEET STACK

Einfach Excel pairs a spreadsheet UI core with a bounded projection contract and a Rust/WASM workbook engine.

This pre-release site presents repository source and interactive demos. It includes local React and Vue controlled-projection islands alongside the Solid demos. No npm-published package or independently verified offline installation is available, and this site makes no support, compatibility, or performance promises.
