What is GRID?
Spreadsheet logic embedded in your product.
Who is GRID best for?
GRID is best for developers building AI agents or apps that need to read, calculate and edit Excel or Google Sheets files.
AI agent builders
Agents call GRID's spreadsheet operations as tools or through an MCP server instead of writing code for each task, which saves tokens and time.
Apps that run spreadsheet models
The headless Spreadsheet Engine calculates Excel and Google Sheets formulas inside your app, in the browser or on a server.
Products that show or edit sheets
A themeable Spreadsheet Viewer and a Spreadsheet Editor scoped to the edits you allow add spreadsheet screens to your own interface.
Excel add-in projects
GRID can power your own Excel add-in, running your domain skills on its engine so the model does not act on the file directly.
How much does GRID cost?
GRID does not publish prices: its packages are free to install under an evaluation license for testing and personal projects, and any commercial use needs a commercial license quoted through a contact form.
GRID has no pricing page. Every npm package ships with a free, full-featured evaluation license for development, testing and personal non-commercial use, which requires a Powered by GRID notice; running GRID in a shipped product or an internal business workflow needs a commercial license, priced on request. Plans and current prices are on grid.is.
