Project overview

It targets the gap between hosted office apps and custom products: an isomorphic SDK that runs UI apps in browsers and headless processing in Node.js with the same architecture, so workbook and document logic can power agents and automation.

Best for

• Developers who need to embed spreadsheet, document, and presentation editing, rendering, and formula computation inside their own product rather than use a hosted app or fixed UI.
• AI engineers and teams building agents, automation, or server-side workflows that manipulate workbooks and documents via a headless Node.js runtime.

Key capabilities

• Open-source spreadsheet capabilities including workbooks, worksheets, ranges, formulas, number formatting, filtering, sorting, data validation, conditional formatting, hyperlinks, comments, find and replace, and tables.
• Every capability is delivered as a composable plugin that can be added, removed, replaced, or lazy-loaded; behavior extends via custom plugins, commands, services, UI components, and Facade APIs.
• Run workbook and document logic in Node.js without UI to power agents, automation, and server-side workflows.
• Canvas-based rendering and a dedicated formula engine keep complex workbooks responsive on large editable surfaces shared across document types.
• One consistent API surface for workbooks, ranges, formulas, and documents across browser and Node.js.
• Preset mode provides curated plugin collections with required Facade API registrations and styles for a working Sheets, Docs, or Node setup with minimal configuration.
• Integrate with React, Vue, Web Components, and framework-specific application shells.
• PDF support is listed as coming soon in the overview.

Limitations and risks

• Real-time collaboration, import/export, printing, charts, pivot tables, and server-side features are Univer Pro commercial features not included in this open-source repository.
• PDF support is listed as coming soon.
• Before adopting or upgrading, verify that all @univerjs/* SDK packages stay in the same coordinated Univer release line on the same version.

Getting started

• Install SDK packages via pnpm and write TypeScript code to register plugins or presets: run 'pnpm add @univerjs/presets @univerjs/preset-sheets-core', import UniverSheetsCorePreset and call createUniver with a container element, then call univerAPI.createWorkbook({}).
