You can convert an Excel spreadsheet to a web app using four methods: Google Sheets (free), Excel Online (free), Convert_ (professional calculators with lead capture), or custom code (free but technical). For customer-facing tools with branding and lead capture, Convert_ is the best option. For quick internal sharing, Google Sheets works in minutes.
1. How to Convert Excel to a Web App with Google Sheets (Free)
The fastest free way is to upload your Excel file to Google Sheets and publish it online.
How it works: Import your file → go to File → Share → Publish to web → copy the link or embed code.
Pros:
100% free
Supports most Excel formulas
Real-time collaboration
Cons:
Looks like a plain spreadsheet
Easy to break formulas
Poor mobile experience
Best for: Quick sharing, simple dashboards, or lightweight internal calculators.
2. How to Convert Excel to a Web App with Excel Online (Free)
Another free option is Excel Online through Microsoft OneDrive.
How it works: Upload your file → open in Excel Online → generate an embed link.
Pros:
Familiar Excel interface
Supports most formulas
Cons:
Still looks like a spreadsheet
Limited customization
No lead capture
Best for: Teams already using Microsoft 365 who need quick sharing.
3. How to Convert Excel to a Professional Web App with Convert_
Convert_ transforms your spreadsheet into a polished, branded calculator or web application. Instead of showing rows and columns, visitors interact with sliders, dropdowns, toggles, and multi-step flows.
JSJ Smart Homes previously managed quoting through spreadsheets. After moving to Convert_, they reduced quoting costs by 97%.
How to convert your spreadsheet:
Prepare your Excel or Google Sheets file with formulas
Add input fields in Convert_ using the drag-and-drop builder (sliders, dropdowns, toggles, file uploads, multi-step flows)
Rename cell names in Convert_ to match your spreadsheet cell references
Add formula fields and paste your formulas (without the = sign)—all formulas work automatically
Customize brand colors, fonts, and design
Embed anywhere: Wix, WordPress, Webflow, Framer, Squarespace, or any platform
Setup time varies: a simple calculator takes around 30 minutes, complex pricing tools can take a few days.
Don't want to build it yourself? The Concierge Service team builds it for you and delivers within 5-10 business days.

4. How to Convert Excel to a Web App with Custom Code
If you're comfortable coding, export your spreadsheet as CSV and connect it to open-source libraries like DataTables.js, Handsontable, or Chart.js. Host free on GitHub Pages.
Pros: Free and fully customizable

Which Excel to Webapp Method Should You Choose?
Need something free and quick? → Google Sheets
Already in Microsoft ecosystem? → Excel Online
Want a professional, branded tool with lead capture? → Convert_ (free tier available, or hand off to Concierge Service)
Have development skills? → Custom code
For businesses, ConvertCalculator offers the best balance of ease, professionalism, and lead generation.
For individuals or one-off projects, Google Sheets is the fastest free option.
When Convert_ Is Not the Right Choice
Convert_ has a learning curve. The platform is powerful and flexible, which means there's more to learn than a basic form builder.
If you just need a simple contact form with a few fields and no calculations, use a simpler tool. If your spreadsheet is simple, purely internal, and customers will never see it, Google Sheets works fine.
Convert_ earns its value when you need customer-facing tools with complex logic, professional design, and lead capture—situations where simple tools hit a ceiling.

How to turn an Excel spreadsheet into an online form?
You can turn an Excel spreadsheet into an online form by connecting your spreadsheet logic to a form builder, or by using a tool that transforms your formulas into interactive inputs directly.
Google Forms + Google Sheets (free, basic): Create a Google Form with your questions → Link it to a Google Sheet → Use spreadsheet formulas to calculate results based on form responses. Limitation: respondents don't see calculations in real time—they submit the form and you process results manually or via email.
Microsoft Forms + Excel (free, basic): Similar approach using Microsoft's ecosystem. Create a form, connect to Excel, process responses with formulas. Same limitation: no real-time calculations visible to the user.
Convert_ (professional, interactive): Paste your Excel formulas directly into ConvertCalculator → Build the form interface with drag-and-drop inputs (dropdowns, sliders, toggles, number fields, file uploads) → Visitors see calculations update live as they fill out the form. Captures leads, integrates with CRMs, and works on any website. This is the only method where your spreadsheet logic runs in real time while users complete the form.
Custom code (technical): Build an HTML form and connect it to your spreadsheet logic using JavaScript. Full control but requires development skills and ongoing maintenance.
If you need a basic form that dumps responses into a spreadsheet for manual processing, Google Forms or Microsoft Forms work fine. If you need an interactive form where users see pricing, quotes, or calculations update as they answer questions, ConvertCalculator turns your Excel formulas into a live, customer-facing experience.

How do I export data from Excel to a web page?
You can export data from Excel to a web page in several ways, from simple copy-paste methods to tools that make your data interactive.
Copy as HTML table (free, quick): Select your data in Excel → Copy → Paste into a web page editor that accepts HTML tables. Many website builders (WordPress, Wix, Squarespace) convert pasted Excel data into basic HTML tables automatically. Quick but static—any updates require manual re-pasting.
Save as HTML file (free, basic): In Excel, go to File → Save As → Choose "Web Page (.htm/.html)" as the format. This creates an HTML file you can upload to your website. The result looks dated and isn't responsive on mobile devices.
Google Sheets publish (free, live updates): Upload your Excel file to Google Sheets → File → Share → Publish to web → Embed on your page. Data updates automatically when you edit the spreadsheet. Still looks like a spreadsheet grid.
Excel Online embed (free, live updates): Upload to OneDrive → Open in Excel Online → Generate embed code → Paste into your website. Similar to Google Sheets—functional but displays raw rows and columns.
Convert_ (professional, interactive): Import your Excel data and formulas → Build an interactive interface where visitors can filter, input values, or see calculations based on your data. Turns static data into dynamic tools like pricing calculators, quote builders, or product configurators with lead capture built in.
For static data that rarely changes, HTML tables or saving as a web page works. For live data that updates frequently, Google Sheets or Excel Online embeds keep your web page synced. For data that needs to be interactive—where visitors input values and see results—ConvertCalculator transforms your spreadsheet into a professional web application.

Can I update my Excel web app after it's built?
Yes. How you update depends on which method you used to create the web app.
Google Sheets: Edit the original spreadsheet and changes appear automatically on your published web page or embed. No republishing required. Anyone with edit access can update the data or formulas directly.
Excel Online: Same as Google Sheets—edit the source file in OneDrive and updates sync to your embedded version automatically. Real-time updates without touching your website.
Convert_: Update questions, formulas, design, pricing logic, and branding anytime using the drag-and-drop builder. Changes publish instantly across all embeds with one click. No coding required, and you don't need to touch your website—the embed pulls the latest version automatically. You can also duplicate calculators to test changes before pushing them live.
Custom code: Updates require editing your code and redeploying to your hosting platform. Changes to formulas or data structure may require updating multiple files. Most time-consuming option for ongoing maintenance.
For simple data updates (changing numbers, adding rows), Google Sheets and Excel Online are fastest—just edit the spreadsheet. For structural updates (adding questions, changing calculation logic, updating design), ConvertCalculator gives you a visual builder where you make changes yourself in minutes. Custom code requires development work for any meaningful update.
