Developers Will Love the Simplicity

Front-end teams or no-code builders simply pass parameters to the API. Complex Excel math becomes instantly available, reducing coding overhead and boosting productivity.

How to turn an Excel model into an API

Fast Iterations and Simplified Maintenance

Editing a spreadsheet is far easier than diving into code. Keep critical formulas in Excel, fix issues quickly, and avoid tying up development resources. Update your spreadsheet, and the API adapts immediately. Ship new features or adjustments without waiting on lengthy redeployments.

Enabling AI Agents
‍to be precise and reliable

AI models predict words, not numbers — which often leads to errors, hallucinations, or missing logic. With SpreadAPI.io, your proven Excel formulas become secure APIs that AI Agents can call for reliable, repeatable calculations. Business experts define the logic, AI consumes it — ensuring precision, compliance, and trust in every result.

Where Our API Shines

Connect your spreadsheet models to any application or AI for reliable, real-time calculations. Chatbots deliver instant quotes or analytics, while your Excel experts—who understand the problems and solutions—publish APIs in minutes. It saves time, boosts accuracy, and eliminates complex code rewrites.
