Univer

Univer is a modular, web-based framework for embedding high-performance office editing suites, including spreadsheets, documents, and presentations, directly into web applications. It utilizes a canvas-based rendering engine to manage complex layouts and large datasets, ensuring consistent performance during user interaction. The system is built on an isomorphic data model that allows the same document logic to function in both browser-based interfaces and headless server-side environments.

The platform distinguishes itself through a command-based state mutation system and a dependency-graph formula engine, which ensure predictable history tracking and efficient calculation of cell relationships. Real-time multi-user collaboration is managed through operational transformation algorithms, which resolve concurrent editing conflicts to maintain data consistency across sessions. A centralized dependency-injection plugin system allows developers to extend core functionality, integrate custom data visualizations, and support specialized file formats.

Beyond its core editing capabilities, the framework provides tools for document lifecycle management, including file import, export, printing, and version history tracking. It supports automated data processing and programmatic document manipulation, enabling developers to build workflows that operate independently of a visual user interface.
