Our solutions
The engine your agents need. The surfaces your users expect.
Engine
Spreadsheet Engine
Spreadsheet logic, running natively inside your application. A headless engine that sits at the core of what we build, and everything you can build with us. Fast, accurate and compatible with Excel and Google Sheets out of the box.
Viewer
Spreadsheet Viewer
A lightweight standalone viewer for displaying spreadsheets inside your product. Fully themeable to match your design system. Works with or without a spreadsheet engine.
Editor
Spreadsheet Editor
A spreadsheet editor that feels at home inside your product. Covers the editing capabilities your users need, without the overhead of a full-blown spreadsheet application.
Excel Add-in
Excel add-in
Your own Excel add-in where the AI has everything it needs to do the job. Proprietary data, business knowledge and custom skills, all available as it generates and edits spreadsheets inside Excel.
Spreadsheets run the world. They hold the models, logic, and workflows that businesses depend on. But they live outside your product, disconnected from your application, hard to integrate, and difficult for AI systems to read, modify, and act on reliably.
With GRID, spreadsheets become a native part of your product. Users work with familiar spreadsheet experiences without leaving your app. AI systems get a structured interface to work with spreadsheet logic directly. And your team ships faster, spending time on what makes your product unique instead of disappearing into the weeds of spreadsheet compatibility and edge cases.

Calculator Studio
Real-time interactivity at animation speed
Calculator Studio is a product that lets anyone build interactive calculators on top of spreadsheets, with sliders, charts, and complex calculations updating in real time as users change inputs. That level of responsiveness is only possible because of how fast the GRID engine recalculates. Every input change triggers a full spreadsheet recalculation at animation speed, keeping even the most complex models fluid and interactive.
Leading AI platforms
The spreadsheet foundation for AI workflows
Frontier AI companies and teams building LLM-powered products alike embed GRID as the foundation for their spreadsheet capabilities. Instead of requiring the LLM to generate and maintain brittle code to read or modify spreadsheets, GRID exposes a structured interface the model can work with directly. That makes spreadsheet-driven AI workflows faster, more reliable, and easier to scale.
The hardest part of integrating spreadsheets is getting started. We’ve made that easy.
Most teams are surprised by how quickly they can go from first contact to a working integration, with direct support from the GRID team throughout.
