Convert Your Excel Spreadsheet to a Web App in Minutes
Your Excel workbook already contains the business logic, formulas, and data. All it needs is a modern interface. With Airrange, you can turn any Excel file into a professional, interactive web app — without writing a single line of code.
What Is an Excel Web App?
An Excel web app is a browser-based application that uses your Excel spreadsheet as its calculation engine. Instead of sharing the raw spreadsheet file, you share a professional interface — with input fields, output displays, charts, and interactive controls — that runs on top of your Excel formulas.
The key benefits:
- Users don't need ExcelThey interact through a web browser on any device
- Your formulas stay hiddenIntellectual property is protected
- Sensitive data can stay localKeep confidential workbooks on your device, no upload needed
- No version chaosEveryone uses the same live application

5 Ways to Convert Excel to a Web App
1. Airrange (No-Code, Excel + Google Sheets)
Best for: Business users who want to turn Excel or Google Sheets into professional web apps without coding.
Airrange works with Excel files (local or Microsoft 365) and Google Sheets (import & sync). You select cells, charts, and ranges, then drag & drop them into an app layout. Excel formulas continue working natively. Apps can be shared via link, embedded on websites, or integrated into Microsoft Teams.
Pros: Zero coding, Excel + Google Sheets, nearly all Excel functions incl. array formulas, sensitive workbooks can stay local, EU-hosted, free to build.
Cons: No offline mode.
2. Google AppSheet (Low-Code, Google Sheets)
Best for: Google Workspace users building mobile-first data apps.
AppSheet creates apps from Google Sheets (and limited Excel support). It has built-in automation bots and offline capability. However, Excel formulas need to be rewritten in AppSheet's expression language.
Pros: Mobile-first, automation bots, offline mode.
Cons: Google ecosystem lock-in, no native Excel formula support, data in Google Cloud.
3. Retool (Low-Code, Developer Tool)
Best for: Development teams building internal tools from databases.
Retool is powerful but requires JavaScript and SQL knowledge. It connects to databases, APIs, and services. Not designed for Excel-based workflows.
Pros: Highly customizable, self-hosted option, connects to any database.
Cons: Requires developers, no Excel formula support, steep learning curve.
4. Glide (No-Code, Google Sheets)
Best for: Teams wanting beautiful mobile apps from Google Sheets.
Glide creates polished mobile-first apps but is focused on data display rather than calculations. Limited formula support compared to Excel.
Pros: Beautiful UI, easy to use, good for directories and CRM.
Cons: No Excel support, limited calculation capabilities, Google-only.
5. Custom Development (Code)
Best for: Organizations with unique requirements and development resources.
Build a custom web app using frameworks like React, Angular, or Vue. Maximum flexibility but requires significant development time and ongoing maintenance.
Pros: Complete flexibility, any technology stack.
Cons: Expensive, slow, requires developers, formula logic must be rewritten.

Frequently Asked Questions
Can I convert any Excel file to a web app?
Yes. Airrange works with Excel workbooks from your device or file server, from Microsoft 365 or as Hosted Files. Nearly all relevant Excel functions are supported — including VLOOKUP, INDEX/MATCH, nested IFs and array formulas. Microsoft 365 workbooks even give you the full Excel Online function set.
Do my users need Excel installed?
No. Users interact through a web browser. They never see or need Excel. The app works on any device — desktop, tablet, or mobile.
Is my data secure?
Yes — and you decide where your workbook lives. Sensitive workbooks can stay on your device or your own servers; they are never uploaded. When you share an app, only an encrypted package with the formulas and data the app needs is created — never the whole workbook. On Enterprise plans, you can even store this package on your own infrastructure. Alternatively, keep workbooks in your own Microsoft 365 tenant or use Hosted Files, encrypted in Frankfurt (EU).
Can I embed the app on my website?
Yes. Every Airrange app can be embedded on any website via an iframe embed code. Apps are fully responsive and adapt to any screen size.
How much does it cost?
You can build unlimited apps for free. To publish and share, paid plans start at €59/month (Pro, 3 published apps, 100 elements).
Can I turn my calculator into a paid product?
Yes. Airrange supports subscription billing via Stripe. Create premium calculators and charge users monthly or weekly.
