# Univer

> Univer Office SDK lets developers build their own AI office environment — an Office Harness. It provides Office editing, calculation and file processing across sheets, docs, slides, canvases, relational tables and PDFs, so people and AI agents (and many agents in parallel) work together inside your product, with your data and existing permissions.

- 39.5k: GitHub stars across Univer and Luckysheet

- Works with your agents: Claude Code, Codex, OpenCode, OpenClaw, Hermes Agent, WorkBuddy, Kimi

## When to use Univer

- Add Office editing to your own web app: sheets, docs, slides, relational tables, canvases and PDFs, embedded in your product and deployed on your own servers.
- Process Office files without an editor: read, edit and fill templates in Node.js, calculate with the Rust formula engine, and import or export XLSX, DOCX, PPTX and PDF.
- Give the agents you already run tools to create, edit and check Office content, with no desktop Office.
- Let people and several agents work on the same content: real-time co-editing, and an isolated worktree per task to compare and merge.

### How to start

- Embed a spreadsheet in a web app: `npm install @univerjs/presets @univerjs/preset-sheets-core` ([Docs](https://docs.univer.ai/overview))
- Process files in Node.js: [Docs](https://docs.univer.ai/guides/sheets/getting-started/node)
- Give a coding agent the Univer CLI skill: `npx skills add dream-num/skills -s univer-cli -g` ([Univer CLI](https://github.com/dream-num/univer-cli))
- Open-source and commercial editions, plans and licenses: [Pricing](https://univer.ai/pricing/index.md)
