Excel to Web: No Coding Required
Turn Your Excel Calculator Into a Lead Generation Machine
If you already built it in Excel, you are one step away from publishing it as an interactive web calculator that drives traffic and captures leads.
The Opportunity
Most Businesses Already Have the Logic Built
People search for interactive calculators constantly. Mortgage estimators, retirement planners, ROI tools, pricing calculators, engineering models. When someone finds a calculator that answers a real question they have, they use it, they bookmark it, and they come back.
Most businesses already have this logic sitting in an Excel file. The formulas are there. The calculations work. The problem has always been getting it onto the web. Traditionally, that meant hiring a developer and rebuilding everything from scratch in code.
SpreadsheetWeb removes that barrier entirely. Upload your Excel file, configure the interface, and publish. Your calculator is live with a shareable link or an embed code for your website in minutes, not months.
Drive Organic Traffic
Interactive calculators consistently rank for high-intent search queries. Visitors looking for answers are the most valuable visitors you can attract.
Capture Qualified Leads
Someone using your calculator is actively engaged with a problem you solve. That is the best possible moment to ask for their contact information.
Protect Your IP
Your formulas and business logic stay completely hidden. Users interact with the results, never the underlying model.

This is a real SpreadsheetWeb application. The formulas running behind it were built entirely in Excel; no code was written to create this web interface.

Building this calculator online was going to cost a lot of money. I found SpreadsheetWeb after a Google search. Low initial and ongoing cost, as well as the simplicity of converting my existing calculator into an application made this a very easy choice.

SpreadsheetWeb hosts this calculator we built and offers it to the world, while protecting our IP and integrity of the tool itself. It also allowed us to convert traffic. We let users get a report and enroll them in our blog, and this turned out to be significant growth for our site.

We could hand the workbook out to customers and email it to them, but we wanted to take it one step further and use SpreadsheetWeb to create a better web version, where we can put it on our website, track its usage, and keep it gated.
