Post Description
SheetMog is an OSS spreadsheet engine which aims for full Excel feature parity behind a headless interface, from the team behind https://shortcut.ai
The engine is built in rust, and can be packaged for web via WASM with typescript GUI.
We have found the API surface to be extremely useful for programming agents or SDKs like Claude Code codex etc...
