Common questions

What is Numio?
Numio is a no-code calculator builder. Import an Excel, CSV, or TSV file, assign cells to input and result blocks, and publish an embeddable web calculator that captures leads. Visitors never see the spreadsheet.
How does Numio work?
You import an .xlsx, .csv, or .tsv file — Google Sheets users export one first — then 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 the Professional and Business 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.
