A cutting-edge spreadsheet engine

Feature-rich. Compatible with Excel and Google Sheets. Animation-speed performance.

Tried and tested

Fully compatible with Excel and Google Sheets, GRID’s spreadsheet engine is the most sophisticated independent spreadsheet engine in the world.

The GRID spreadsheet engine powers Calculator Studio–our SaaS platform that enables users to convert spreadsheets into interactive calculators through an easy-to-use WYSIWYG editor.

Every build is automatically tested against thousands of real-world spreadsheets with a broad range of complexity, utility and use-cases to ensure accuracy and performance.

Transforms spreadsheets into web services

Designed for flexibility, our powerful spreadsheet engine runs your spreadsheet models in the cloud, allowing you to integrate spreadsheet logic directly into your applications without the need for a traditional spreadsheet interface.

Recalculations without data overwrites

Once you upload your spreadsheet to our API, it’s kept separate from ongoing calculations. This lets you adjust inputs and test various outcomes, knowing your original data is preserved. Test scenarios and explore different outcomes while preserving the integrity of your models.

Natural language, reliable answers

As LLMs transform online interactions, spreadsheets remain the cornerstone of business planning and decision making, where accuracy and consistency are crucial. The GRID Spreadsheet Engine bridges these worlds, integrating with LLMs to create the perfect synergy: intuitive, natural language interaction paired with fast, reliable results.
