Google Sheets is great when a product is still changing.
It is fast.
It is familiar.
Non-technical people can edit it.
You do not need to design a full database schema on day one.
For many MVPs, internal tools, client portals, and small SaaS experiments, that flexibility is exactly what makes Google Sheets useful.
But there is one mistake I see often:
Connecting the frontend directly to Google Sheets.
At first, it feels simple.
Your React app fetches rows from a sheet.
Your users see the data.
Your team can edit content without touching code.
Everything feels lightweight.
Until the spreadsheet quietly becomes part of your production architecture.
The problem
Once your frontend depends directly on Google Sheets, your sheet is no longer just a spreadsheet.
It becomes your backend contract.
That is where things start to break.
Columns get renamed.
Tabs move.
Permissions become unclear.
Data types drift.
Someone changes status to Status.
Someone adds a new column in the middle.
Someone deletes a tab because they thought it was unused.
And suddenly your frontend is broken because it was coupled to the spreadsheet structure instead of a stable API contract.
This is the real issue.
Not that Google Sheets is bad.
The issue is that the frontend should not know too much about how the data is stored.
The better boundary
Instead of this:
Google Sheets → Frontend
I prefer this:
Google Sheets → API layer → Frontend
The frontend should not care whether the data comes from Google Sheets, Postgres, MongoDB, Airtable, Supabase, or something else later.
It should care about the API contract.
For example, the frontend should request something like this:
GET /api/products?status=active&limit=20
And receive something predictable:
{
"data": [
{
"id": "prd_001",
"name": "Starter Plan",
"status": "active",
"price": 19
}
],
"meta": {
"limit": 20,
"count": 1
}
}
The frontend should not need to know:
- which spreadsheet tab contains the data
- which column index stores the price
- whether the source is still Google Sheets
- how authentication with Google Sheets works
- how to handle spreadsheet-specific errors
That logic belongs behind an API layer.
What the API layer should handle
A good API layer gives your app a safer boundary.
It can handle things like:
- authentication
- schema detection
- CRUD endpoints
- pagination
- filtering
- sorting
- field selection
- relation expansion
- caching
- usage limits
- permissions
- error formatting
- future migration
This matters because most MVPs do not fail because they chose the wrong database on day one.
They fail because the product changes faster than the architecture can handle.
An API boundary gives you room to change the backend without constantly breaking the frontend.
Why this matters for MVPs
I do not think every MVP needs Postgres on day one.
Sometimes that is overengineering.
If the product is still being validated, the data model is still changing, and non-technical users need to edit data quickly, Google Sheets can be a very practical starting point.
But that does not mean your frontend should be tightly coupled to it.
There is a middle path:
Start with Sheets.
Expose a stable API.
Move to a real database when the workload deserves it.
That approach lets you move fast without pretending the spreadsheet is your final infrastructure.
The hidden benefit: migration becomes easier
One underrated benefit of an API layer is migration.
If your frontend talks directly to Google Sheets, migrating later means changing frontend logic everywhere.
But if your frontend talks to an API, migration becomes much cleaner.
Today:
Google Sheets → API → Frontend
Later:
Postgres → API → Frontend
The frontend can stay mostly the same because the contract stays the same.
That is the point of the boundary.
You are not just adding an API for today.
You are buying flexibility for tomorrow.
What I’m building
This is the space I am exploring with TarangDB.
TarangDB is my attempt to build the backend layer for teams that start with Google Sheets but need something safer than direct spreadsheet access.
The goal is not to replace Postgres, Supabase, Firebase, or a real production database.
The goal is simpler:
Help teams start with Google Sheets, expose a secure REST API and dashboard, and migrate later when the product actually needs a dedicated database.
In other words:
Google Sheets as the starting point.
API contracts as the boundary.
Real databases when the product is ready.
The question I keep thinking about
Google Sheets is not always the wrong choice.
But direct frontend access usually becomes painful at some point.
So I am curious:
Have you ever connected a frontend directly to Google Sheets, Airtable, or another spreadsheet-like tool?
What broke first?
Was it schema changes, permissions, performance, validation, or migration?
I am building TarangDB in public and looking for feedback from developers, indie hackers, and agencies who have used spreadsheets as an early backend.
The main thing I am trying to learn is:
At what point does Google Sheets stop being “good enough” for your MVP or internal tool?

I’m building in this space right now, so I’d love to learn from other people’s experience.
For those who have used Google Sheets, Airtable, or a spreadsheet-like tool as an early backend:
What was the first thing that became painful?
I’m especially curious about the “middle stage” — when a spreadsheet is still useful, but direct frontend access starts to feel risky.
