Common questions

What is Numio?
Numio is a no-code platform that turns a spreadsheet (Excel or Google Sheets) into an interactive web calculator you can embed anywhere. You import your model, choose which cells are inputs and which are results, add blocks, style it, publish, and embed.
How does Numio work?
You import your Excel or Google Sheets model, choose which cells are inputs and which are results, add blocks, style it, publish, and embed. The underlying spreadsheet and formulas stay private; the math recomputes live in the visitor's browser, and visitors only see the blocks you expose.
How much does Numio cost?
Numio has three plans: Starter $120/mo, Professional $350/mo, and Business $600/mo, with about 30% off annual billing. Every plan includes unlimited projects and responses. There is a 14-day trial with $0 due today. Enterprise offers custom seats, SSO, onboarding, and volume pricing.
Can I embed a Numio calculator on my website?
Yes. Numio publishes calculators as public links, tracking links, and iframe embeds, with versioning. The Numio watermark can be removed on paid plans.
Does Numio keep my spreadsheet and formulas private?
Yes. The underlying spreadsheet and formulas stay private. The math recomputes live in the visitor's browser, and visitors only see the blocks you choose to expose.
