GRID — Spreadsheet Engine API

Spreadsheets as APIs

Turn spreadsheets into powerful web services

GRID's advanced spreadsheet engine converts your spreadsheets into flexible, cloud-based web services, ready for integration into AI workflows and other applications. Fully compatible with Excel and Google Sheets, it brings the familiarity of traditional spreadsheets into a modern, cloud-native environment.

With a RESTful API, you can seamlessly integrate existing business logic into your applications, eliminating the need to rebuild complex calculations. This accelerates development, enhances reliability, and ensures the depth and accuracy of your data models remain intact.

Preserve your data

No permanent rewrites

We keep your original data unchanged, even when you change inputs. When you adjust values in your model, our spreadsheet engine recalculates the results without altering the original spreadsheet. This allows you to run different scenarios without exposing or affecting your base data models.

Whether you're evaluating investment strategies, running sensitivity analyses, or assessing potential sales targets, being able to adjust inputs and instantly see results—while keeping the underlying data intact—gives you flexibility without compromising accuracy.

Ready for AI

Unlock the language of numbers

Large language models like OpenAI’s ChatGPT are great at generating text and handling simple spreadsheets in tabular form, but they struggle when it comes to more complex spreadsheet models. With GRID, you can turn your spreadsheets into web services and integrate your models to your AI and LLM projects in a simple way. This enables your AI to answer complex, model-driven questions in natural language, turning your spreadsheets into a powerful tool for reliable, dynamic responses. With GRID’s spreadsheet engine, you can create spreadsheet-powered AI for the first time ever.
