How Airrange's Calculator Builder Works
Your Excel spreadsheet already has the calculation logic. Airrange adds the interface. Here's how:

- Open in Airrange — Select input cells (sliders, dropdowns, text fields) and output cells (results, charts).
- Design the interface — Drag & drop elements. Add labels, rich text, branding.
- Embed on your website — Get an iframe code and paste it into any page. Fully responsive.
