Your spreadsheet, rebuilt as a secure app that doesn't break
The shared spreadsheet that runs your business is fragile. One wrong click overwrites it, formulas break, and anyone with the link can see everything. We rebuild it as a web app with logins and validation, with your data intact, so it stops breaking as your team grows.
Turning a spreadsheet into a web app means we take the Excel or Google Sheet your business already runs on and rebuild it as a secure, multi-user application. Your data and structure stay, and the app adds logins, roles, data validation, search, import and export, audit logs, and dashboards. You keep what makes a spreadsheet convenient and lose the overwritten cells, the broken formulas and the missing record of who changed what. It typically starts around US$1,500. If you need a login area for clients or staff, see business portals.
Signs your spreadsheet has become a liability
A spreadsheet is a good place to start a business. The things that made it easy (anyone can open it, anyone can change any cell) are what make it risky once money and several people depend on it. If the signs listed here feel familiar, the sheet has started costing you.
A single wrong click can overwrite hours of work, and there is no undo once it is saved and shared.
Formulas silently break and nobody notices until a total is wrong in front of a customer.
There is no record of who changed what, or when, so mistakes turn into guesswork and blame.
You cannot control who sees which rows or columns; opening the file means opening everything.
It has grown so big it is slow to load, slow to scroll, and a little frightening to touch.
Duplicate and inconsistent entries are everywhere, the same customer spelled three different ways.
To check whether you have reached that point, read the signs your business has outgrown spreadsheets, or see the bigger picture in our guide to replacing spreadsheets.
What a spreadsheet-to-app conversion includes
You keep the same data and the same familiar structure. It now sits on a database, with the access controls and checks a growing business needs.
Keep your structure
We import the data you already have and keep the columns and categories your team knows. Nobody has to relearn the layout, and your history comes with you.
Logins and roles
Each person signs in and sees only what they should. The front desk, the manager and the owner can each have a different view, so the whole file no longer gets emailed to everyone.
Data validation
Fields check themselves as people type, so dates are valid dates, prices are numbers, and required information is not left blank. Bad and duplicate entries are caught at the point of entry.
Search and filter at scale
Find a record in seconds across thousands of rows, filter by status, date, or person, and stop scrolling endlessly or hunting through five tabs to answer one question.
Import and export
Bring your existing sheet in at the start, and pull clean data back out to Excel or CSV whenever you need it for your accountant or a report. You can take your data out at any point.
Audit logs and dashboards
A log of who did what and when, plus live dashboards that turn your rows into the totals, counts and trends you report on, without an hour of work in Excel.
Need staff or clients to log in and submit their own records? That's a business portal. Need to generate quotes, invoices, or letters from your data? That's document automation.
The six steps of a spreadsheet conversion
Six steps take you from the file you have today to the app your team logs into, and your data is carried across along the way.
We review your spreadsheet
We sit with your current Excel or Google Sheet and watch how your team uses it (the tabs, the colour codes, the workarounds) so the app fits the way you already work.
We design the data model behind it
We turn a flat grid of cells into a proper structure: customers, jobs, items, payments, and how they relate. This is the part that makes search, roles, and reporting possible later.
We import your existing data
Your existing records move into the new app, cleaned of obvious duplicates and inconsistencies along the way, so you launch with your history intact.
We build the app with roles, validation, and dashboards
We add the logins, permissions, validation rules, search, and the dashboards your team needs. These are the controls a shared spreadsheet does not have.
We test, launch, and train your team
We check it against your own data, roll it out, and show your people how to use it day to day, to keep the switch from interrupting their work.
We host and maintain it (optional)
If you want, we keep it hosted, secure, backed up, and updated as your business changes, or we document it and hand it over to you.
The shared spreadsheet today
- Anyone with the link can see and edit everything
- One bad paste overwrites work with no undo
- No record of who changed a number, or when
- Slows to a crawl once it gets big
- Duplicates and typos multiply
The same data, as a secure app
- Everyone logs in and sees only their part
- Validation stops bad and duplicate entries
- Every change is logged with who, what and when
- Searches thousands of records in seconds
- Exports clean back to Excel whenever you need
Turning a spreadsheet into a secure internal app typically starts around US$1,500 and runs up to about US$4,500, depending on how many users and roles you need, how complex the data is, and whether it connects to other systems. We scope it against your own spreadsheet first, so the quote is based on your file.
Need to also generate quotes or invoices from that data? See document automation.
