Open-source spreadsheet engine aims to fix Excel chaos with contracts and extensions
A developer open-sourced a Rust-based spreadsheet engine after his startup failed, aiming to solve the problem of managing hundreds of near-identical Excel files. The engine supports formula calculation, OOXML compatibility, and undo/redo, with a Block system to define stable data structures and a Craft extension system for custom automation. The project leverages AI to accelerate development, now offering a core that can run independently from the frontend for background processing.

The approach of treating spreadsheets as structured systems with contracts is promising, but the real test will be adoption and whether the extension ecosystem can compete with entrenched tools like Excel and Google Sheets.
