## What it is
Univer is a full-stack, isomorphic TypeScript SDK for building embeddable office applications - spreadsheets, documents, and presentations - that run in both the browser and Node.js. It uses a microkernel and plugin architecture with Canvas-based rendering, a formula engine, and a unified Facade API, with optional real-time collaboration.

## Use cases
- embed an Excel-like spreadsheet editor in a web app
- build a Word-like rich text document editor in the browser
- add a PowerPoint-like slide editor to my product
- edit xlsx files on the server with Node.js
- add real-time collaborative editing to spreadsheets
- build a low-code table-driven business app
- generate or manipulate office documents programmatically

## When to choose
- you need embeddable, customizable spreadsheet/document/presentation components rather than a hosted office suite
- you want the same office SDK to work in the browser and on Node.js
- you need a plugin architecture to extend or customize office editing features
- you want real-time collaboration with conflict resolution built in

## When to avoid
- you just need to parse or convert office files without editing UI
- you need a fully finished end-user office product rather than an SDK to build one
- you require pixel-perfect compatibility with complex legacy Office file features
- your project must support very old browsers or Node.js versions below 18.17
