Installing packages

Every GRID product ships a free evaluation package on npm, with no signup and no token required. Pick the package for what you’re building and run the install command below. (The full commercial packages are private and need a token, see below.)

Engine

A headless, Excel-compatible calculation engine for the browser, on-device, or server.

npm install @grid-is/spreadsheet-engine

Viewer

Display spreadsheets inside your React app, read-only, with no backend.

npm install @grid-is/spreadsheet-viewer

Editor

A scoped, familiar spreadsheet editing experience for React.

npm install @grid-is/spreadsheet-editor

Agent Tools

Let an AI agent read, calculate, and edit spreadsheets. Run it as an MCP server:

claude mcp add grid -- npx -y @grid-is/agent-tools

Or import the tools into your own agent SDK:

npm install @grid-is/agent-tools

Building with an AI agent?

Hand GRID’s spreadsheet skills to your coding agent, then ask it to build. Works in Claude Code, Codex, Cursor, and anywhere agent skills are supported. There is one skill per task, so pick the one you need:

npx skills add GRID-is/spreadsheet-skills --skill spreadsheet-engine

Or choose interactively:

npx skills add GRID-is/spreadsheet-skills

The skills README lists every skill and the package it covers.

Licensing

The evaluation licence covers the engine, viewer, and editor packages. It is free and fully featured for internal evaluation, and for personal, educational, or other non-commercial use by an individual. Shipping a commercial product, or running GRID in production or in any revenue-generating workflow, requires a commercial licence.

Commercial packages

Commercial licences ship the full packages (@grid-is/apiary, @grid-is/mondrian-react, and @grid-is/editor), which are private on npm. To install them you need an npm auth token. Create an .npmrc file in your repository root (or in another supported location) and add:

.npmrc

//registry.npmjs.org/:_authToken=${NPM_TOKEN}
@grid-is:registry=https://registry.npmjs.org/

Note

This assumes you already have an environment variable, NPM_TOKEN, that gives you access to the commercial packages on npmjs.com. If you don’t have a token yet, talk to us about a commercial licence.
