Univer Office SDK

Univer is an open-source, isomorphic SDK designed for building spreadsheet, document, and presentation experiences. It is a framework for building productivity surfaces rather than just a file viewer.

Key capabilities include:

• Embeddable UI: Integrate spreadsheet or document editing into SaaS products, BI workflows, or AI applications.
• Isomorphic Execution: Run the same architecture in the browser for UI or in Node.js for headless server-side processing (e.g., for AI agents or automation).
• Plugin Architecture: Compose, replace, or extend features using a plugin-first approach.
• Unified API: Access workbooks, ranges, formulas, and documents through a consistent Facade API across different environments.

The @univerjs/docs package provides the document data model and core rich-text operations for Univer Docs. It is designed to be independent of the UI layer.

@univerjs/docs-ui provides the editor UI layer for Univer Docs. Its core responsibilities include:

• Selection rendering
• Clipboard support
• Menus
• Document interaction services

The @univerjs/preset-sheets-note package provides a pre-configured preset for adding note functionality to Univer Sheets.

It includes support for:

• CSS: Styles are provided.
• Locales: Internationalization support is included.
• Facade entry: Accessible via the Univer Facade API.

The @univerjs/engine-render package is Univer's canvas rendering engine. It manages the following core responsibilities:

• Document layout
• Rendering primitives
• Interaction layers
• Scrolling
• Zooming

The @univerjs/preset-sheets-drawing package provides a pre-configured set of features for drawing capabilities within Univer Sheets.

When using this preset, the following assets are integrated:

• CSS: Yes
• Locales: Yes
• Facade entry: Yes

The @univerjs/core package serves as the foundation of the Univer ecosystem. It provides the following essential services:

• Univer Runtime: The central execution environment.
• Dependency Injection: For managing service lifecycles and dependencies.
• Command and Mutation Services: For handling state changes and operations.
• Data Models: The underlying data structures for Univer.
• Configuration and Localization: Global settings and language support.
• Facade Entry Point: The shared interface used by higher-level packages to interact with the core.

Univer is an open-source, isomorphic office SDK designed for building embeddable spreadsheet, document, and presentation experiences. It is compatible with both browsers and Node.js environments.

Core Capabilities

• Runtime & Infrastructure: Includes a plugin system, command and service infrastructure, a Facade API, a formula engine, and a Canvas rendering engine.
• Office Models: Provides composable models and editing capabilities for Sheets, Docs, and Slides.
• Shared Features: Includes shared drawing, commenting, data validation, formatting, and localization infrastructure.
• Integration Paths: Supports Browser, Node.js, and Web Worker environments. It provides React-based UI components and adapters for Vue 3 and Web Components.

The @univerjs/action-recorder package allows you to record user actions within Univer. These recorded actions can be replayed for several purposes:

• Debugging: Reproduce specific user behaviors to find bugs.
• Demos: Show specific workflows in a controlled manner.
• Automated Workflows: Reproduce sequences of actions for automation.

The @univerjs/engine-formula package serves as Univer's formula runtime. Its core responsibilities include:

• Parsing formulas
