Excel rater to broker quote portal
Keep the actuary's rating model in Excel behind your broker portal or partner API.
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. The hosted API and bulk scenarios are live. Choose your use case below, then start a free trial or read the API docs. Web forms stay on the home-page waitlist.
