About univer
Univer is an open source, full stack office SDK for building spreadsheet, document and presentation interfaces inside your own product. Rather than shipping an end user office suite, it gives developers the primitives — a Canvas based renderer, a formula engine, a plugin architecture and a single Facade API — to embed spreadsheet and document editing into a web application or run the same logic headlessly on Node.js.
