Convert Excel to a Web App
Convert Excel to a web app and the spreadsheet everyone emails around becomes a tool your team logs into — from a browser, an Android phone, or an iPhone. Upload the file, keep the columns and the logic, add who can view and who can edit. No developer, no rebuild from scratch.

How to convert an Excel spreadsheet to a web application
Converting an Excel spreadsheet to a web application takes four steps, and you do all of them in a chat window.
Upload the .xlsx
Drop in the workbook you use today. AgentUI reads the sheets, the columns, and the data types.
Describe what it should do
Say it in plain language: who fills it in, what has to be validated, what should never be editable.
The app gets built
You get a real database, forms, filters, and a dashboard — not a spreadsheet with a nicer skin.
Invite your team
Set roles, share the link, and the app is live. Every edit is recorded in the audit log.
02
What you can build from an Excel file: trackers, CRMs, online calculators
These are the spreadsheets people create an app from most often. If yours isn't listed, it still works — the pattern is the same.
Inventory tracker
Stock counts that update live instead of a sheet someone reconciles on Fridays.
Order management
Order sheets become a queue with statuses, owners, and no duplicate rows.
Customer database
A contact list becomes a searchable CRM with notes and history.
Online calculator
Turn the pricing or quoting formulas in your workbook into a calculator your team — or your customers — can use in a browser.
Project and task board
Task lists become a board with assignees, due dates, and reminders.
Budget dashboard
Expense tabs become a dashboard that refreshes itself instead of a monthly rebuild.
03
Built for the person who owns the spreadsheet
If you're the one people message when the file breaks, moving from spreadsheet to app is what takes that off your desk. You know VLOOKUP and pivot tables. You do not want to learn a framework.
Eight versions of one file
final_v3_REAL.xlsx. Nobody is sure which one the numbers came from. One shared database ends the argument.
No permissions, no audit trail
Anyone with the file can overwrite anything. In an app you set roles, and every change is logged with who and when.
One person holds it together
The macros only make sense to whoever wrote them. An app your team can actually operate is not a fragile dependency.
04
Your Excel sheet, working on Android and iPhone
Excel on a phone is pinch-and-zoom punishment, which is why people search for a way to get an Excel sheet to an Android app. What you get here is a web app that installs to the home screen and works on any phone or tablet — the warehouse counts stock on their phone, the field team submits from the van, and it lands in the same database you look at on your laptop. No app store, no separate build for iOS and Android.

Excel vs. a web app: what actually changes after you convert
| Excel file | AgentUI web appBetter value | |
|---|---|---|
| Editing at the same time | One writer, others read-only | Everyone, live |
| Who can see what | Whoever has the file | Roles per user and per field |
| History of changes | Not recorded | Audit log: who, what, when |
| On a phone | Pinch and zoom | Built for the screen |
| Data validation | Cell rules people bypass | Enforced by the app |
| Connecting other systems | Copy and paste | SQL and API integrations |
| Cost to start | Already paid for | Free plan, $0 |

Convert Excel to a web application free, and upgrade only if you outgrow it
The Free plan is $0 a month with 1 member and 3 projects — enough to convert a real spreadsheet, use it, and decide whether it's worth paying for. When you need more people in it, Solo is $25/mo and Builder is $49.99/mo for a team of 2 with 10 projects. And you are not left alone with it: white-glove onboarding means a human helps you get the first tool right, so the app never becomes another thing only one person understands.
Send us the spreadsheet. Get the web app.
Start with the workbook that hurts the most. You'll know within an afternoon whether the app is better than the file.
