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 Excel — They interact through a web browser on any device
Your formulas stay hidden — Intellectual property is protected
No version chaos — Everyone uses the same live application
Embeddable — Put calculators, tools, and dashboards on your website
Mobile-friendly — Responsive apps that work on phone, tablet, and desktop

5 Ways to Convert Excel to a Web App

1. Airrange (No-Code, Excel-Native)

Best for: Business users who want to keep their Excel formulas intact and create professional web apps without coding.

Airrange works directly with your Excel files — local or in Microsoft 365. You select cells, charts, and ranges, then drag & drop them into an app layout. All formulas continue working. Apps can be shared via link, embedded on websites, or integrated into Microsoft Teams. Your files never leave your device.

Pros: Zero coding, full Excel compatibility, EU-hosted, free plan available.
Cons: No offline mode, focused on Excel (not Google Sheets).

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.
