WorkbookAPI

Where does your Excel model need to work?

WorkbookAPI checks your Excel model in the browser for free before you use it in a website, app, API, or scenario workflow. See which formulas compute exactly like Excel. The workbook never leaves your browser during the check; only anonymous totals are counted. APIs, web forms, and bulk scenarios are planned for early access and are not yet available. Choose your use case below, then check your workbook and join the waitlist on the home page.
