GRID

GRID is a powerful spreadsheet engine designed to bring spreadsheet logic into modern applications and AI workflows. It is fully compatible with Excel and Google Sheets, enabling users to run complex models with fast, reliable calculations. GRID supports integration through a JavaScript library for on-device or on-premise use, as well as a cloud-hosted REST API for quick deployment and AI integration. This flexibility allows developers to embed spreadsheet calculations directly into apps, chatbots, and automation tools without rewriting formulas. The platform targets developers and businesses that rely heavily on spreadsheets for critical operations, offering a way to automate and scale spreadsheet logic while maintaining data privacy and control. GRID’s engine preserves original spreadsheet data by performing dynamic recalculations without altering source files, ensuring safety and consistency. GRID stands out by enriching spreadsheets with language data, making it easier for AI systems to understand and interact with spreadsheet content. This capability supports advanced use cases like integrating spreadsheets with large language models (LLMs) and building AI assistants that can query and update spreadsheet data naturally. The engine undergoes extensive testing with nearly 200,000 automated unit tests and benchmarking against real-world workbooks to ensure accuracy and performance. It supports over 450 spreadsheet functions and advanced features like named ranges and dynamic dependencies, making it suitable for complex business models. Beyond the engine, GRID offers Calculator Studio, a no-code product that lets users create interactive web calculators powered by spreadsheet logic. This complements the engine by providing a user-friendly way to build calculators without programming. Overall, GRID helps organizations leverage their existing spreadsheet investments by turning them into scalable, AI-ready web services and integrations. It addresses common challenges like version control, secure sharing, and collaboration by embedding spreadsheet logic directly into applications and workflows.
