How to Convert Excel to a Web App (5 Ways Compared)

Your Excel spreadsheet works. It tracks your clients, manages your inventory, or runs your project schedule. But it’s breaking at the seams — shared access is a nightmare, there’s no mobile version, and one wrong edit can destroy hours of work.

You need a web app. Here are five realistic ways to get one from your existing spreadsheet, ranked from most effort to least.

1. Build It Yourself with Code

Cost: Free (your time) Timeline: Weeks to months Skill needed: Full-stack development

If you can write code, you can build a web app from scratch using your spreadsheet as the data model. Parse the columns into a database schema, build a frontend, deploy it.

Pros: Total control, no vendor lock-in Cons: Requires significant development expertise and ongoing maintenance

Realistic for: Developers who want a side project. Not realistic for business owners with no coding experience.

2. Use Google AppSheet

Cost: ~$5/user/month Timeline: Hours to days Skill needed: Medium — data modeling, formula logic

Google’s AppSheet connects directly to Google Sheets and generates a mobile-friendly app. You configure views, forms, and workflows through a visual interface.

Pros: Direct Sheets integration, mobile-ready, Google ecosystem Cons: Requires understanding of data modeling concepts, limited UI customization, apps look generic

The catch: AppSheet expects you to think about data relationships, slice filters, and action configurations. If “normalization” and “virtual columns” aren’t in your vocabulary, you’ll hit a wall.

3. Use Glide

Cost: ~$25/month per app Timeline: Hours to days Skill needed: Medium — visual builder with logic configuration

Glide is more visual than AppSheet. Connect a Google Sheet, drag components onto screens, configure data bindings. The result looks polished.

Pros: Beautiful templates, quick to prototype, good mobile experience Cons: Template-based (limited custom layouts), gets expensive with multiple apps, still requires you to design the app yourself

The catch: You choose what screens exist, what data appears where, and how navigation works. Glide makes the building easier, but the designing is still on you. If you don’t know what screens your app needs, Glide can’t tell you.

4. Use Softr

Cost: ~$49/month Timeline: Hours to days Skill needed: Medium — visual builder, Airtable knowledge helpful

Softr works well with Airtable (and Sheets via integration). It’s strongest for client portals, directories, and internal tools. Pick a template, connect your data, customize.

Pros: Professional-looking templates, good for portals, membership features built in Cons: Template constraints, requires Airtable for best experience, limited workflow automation

The catch: If your spreadsheet doesn’t map cleanly to Softr’s template categories, you’ll spend more time fighting the tool than building with it.

5. Have It Built For You (AI-Powered)

Cost: ~$2,000 one-time + hosting Timeline: 5–7 business days Skill needed: None

This is the newest approach. Upload your spreadsheet to a service like SheetSmith, answer questions about what you need, and receive a fully custom web app — built by AI, polished by a human developer.

Pros: Zero technical skill required, fully custom (not template-based), human quality review, ongoing AI-powered changes Cons: Higher upfront cost than self-service tools, 5–7 day wait for delivery

The difference: You don’t design the app — the AI interviews you to discover what you need, including features you didn’t think to ask for. Then a human developer reviews everything before delivery.

Approach	Cost	Timeline	Skill Needed	Customization	Ongoing Effort
Code it yourself	Free	Weeks–months	High	Unlimited	You maintain it
AppSheet	$5/user/mo	Hours–days	Medium	Configurable	You manage it
Glide	$25/mo	Hours–days	Medium	Template-based	You manage it
Softr	$49/mo	Hours–days	Medium	Template-based	You manage it
AI-powered (SheetSmith)	$2,000 + $99/mo	5–7 days	None	Fully custom	Managed for you

How to Decide

Ask yourself two questions:

1. Can I design the app myself?

If you know what screens you need, what data goes where, and how users navigate through it — a self-service tool (AppSheet, Glide, Softr) will save you money. You’ll spend a few hours configuring it.

If you’re thinking “I know what my spreadsheet does, but I have no idea what the app should look like” — that’s normal. Most people can describe their problem but not the solution. That’s where an AI-powered service helps, because it asks the right questions to figure out the design for you.

2. How much is my time worth?

Self-service tools are cheaper per month but cost your time. If you spend 20 hours learning AppSheet and configuring your app, and your time is worth $75/hour, you’ve spent $1,500 in time plus the ongoing subscription.

A done-for-you service costs more upfront but gives you those 20 hours back.

The Spreadsheet Migration Checklist

Before converting your spreadsheet, regardless of which approach you choose:

Clean your data. Remove duplicate rows, empty columns, and test data
Document your formulas. Which calculations are critical? What triggers what?
List who uses it. Who reads the data? Who edits it? Who needs what access?
Identify the pain points. What breaks? What’s slow? What’s missing?
Describe the dream version. If the spreadsheet could do anything, what would you add?

That last question is the most important. The answer tells you whether you need a simple data viewer (AppSheet is fine) or a real custom application (you need something more powerful).
