GRID spreadsheet API

What it does

Power your AI projects, workflows and software with the spreadsheets you trust. GRID turns your spreadsheets into fast, scalable RESTful APIs to integrate Excel and Google Sheets business logic into your applications - no need to rewrite spreadsheets as code.

GRID is the spreadsheet engine for agentic products. Install from npm with a free evaluation license, build with your agent, and license commercially when you ship.

Agents call spreadsheet operations directly instead of burning tokens generating code. Ready-made, familiar UI for when humans need to read or edit. Fast, rigorously tested, and quick to integrate. A coding agent built this on top of a financial analyst's Excel model. Drag the sliders and watch the GRID engine recalculate hundreds of cells in real time. Spreadsheet logic and calculations, running natively inside your application. Headless, fast, and fully compatible with Excel and Google Sheets out of the box. Agent Tools run on the same engine, so your agents read, calculate, and edit spreadsheets directly instead of generating code. The GRID engine lets LLMs work directly with spreadsheet…from grid.is
