Is Google Sheets good for a database?
It depends — and anyone who says "always" or "never" is selling something. Here is a straight assessment of Google Sheets as a database, with the failure modes named up front.

Key facts
- Good for: read-mostly data, under ~10,000 rows, edited by humans, where a non-engineer owning the data is the whole point.
- Bad for: user accounts, anything transactional, high write concurrency, or personal data — a sheet has no row-level permissions.
- A Google Sheet is capped at 10 million cells (or 18,278 columns), which is the real ceiling on using one as a database. source

The Google Sheets API allows 300 read requests per minute per project and 60 per minute per user. Past that it returns
429 RESOURCE_EXHAUSTED. source
Is Google Sheets good for a database?
Google Sheets is a good database when your data is tabular, read-heavy, modest in size, and edited by people rather than machines. It is a bad database when you need transactions, high write concurrency, strict schemas, millions of rows, or relational joins.
Most people asking this question are in the first camp and do not realise it. If a spreadsheet is already where the data lives, and your app only ever reads it, then the spreadsheet is not a compromise — it is the friendliest editing interface you will ever ship. What it needs is a fast, cached API in front of it, not a migration to Postgres.
Green flags
- Under ~10k–50k rows and mostly reads.
- Humans editing content; changes are occasional, not per-second.
- You value "anyone can edit it in a familiar tool" over raw performance.
Red flags
- Concurrent writes, financial data, or anything needing transactions.
- Complex relationships across many tables.
- Strict validation and row-level permissions.
How to do it safely
Put a REST API in front of the sheet (so apps query rows, not cells), cache reads, and add schema drift alerts and schema lock so a renamed column does not silently break consumers. That covers the two things people usually regret: performance and schema surprises. Start with using Google Sheets as a database.
Frequently asked questions
Is Google Sheets good for a database?
Yes for tabular, read-heavy, human-edited data at small-to-medium scale. No for transactions, high write concurrency, huge datasets, or complex joins.
How many rows can it handle?
It works comfortably into the tens of thousands of rows for reads. Beyond that, or for heavy writes, move to a traditional database.
How do I avoid breaking my app when the sheet changes?
Use schema drift alerts and schema lock so a renamed or removed column raises an alert or a clear error instead of silently serving the wrong shape.
