About this Gig
Google Sheets is great until it isn't. If your business runs on it, you've probably hit some of these:
- One wrong click and a formula breaks
- Clients see raw rows and columns, not something that looks professional
- Not easy to use on a phone
- No validation, so bad or incomplete data gets entered
- No notification automatically when something changes
I fix these by building a web app on top of your existing sheet. he best part is that this web app is built and runs entirely inside the existing Google Sheet setup. No external servers, no paid tools, no new accounts. Your sheet stays as the backend, nothing about your data structure changes, but the way people interact with it does.
Here is what that looks like:
- Google login, so only the right people can access it
- A clean form, dashboard, or calculator instead of raw spreadsheet rows
- Mobile-friendly interface
- Input validation before anything reaches your sheet
- Automated email alerts tied to form submissions or updates
This is a good fit if you are already using Sheets and want it to function like a real tool instead of a shared spreadsheet.

FAQ
Does this replace my Google Sheet, or work alongside it?
It works alongside it. Your sheet remains the actual data storage. The web app is just a different way for people to view or interact with that same data.
Can multiple people use the app at the same time?
Yes. Apps Script handles multiple simultaneous users, though very high traffic (hundreds of users at once) can slow things down since it's not built for large-scale hosting.
Will this work with Excel too, or only Google Sheets?
The web app itself is built using Google Apps Script, so it connects directly to Google Sheets. If your data is in Excel, I can help you move it into Sheets first.
Do I need to give you edit access to my Google Sheet?
Yes, I'll need edit access to connect the web app to your sheet and set up the required scripts. You can revoke access once the project is delivered if you prefer.
Does the web app work without internet access?
No. Since it's connected live to Google Sheets, it requires an internet connection to load and save data.
