Google Sheets API
Google Sheets API
Google Sheets API lets apps read and write Google Sheets — commonly used as a lightweight database or as a bridge to external systems.
Generous per-user quota
Up to 10M cells per spreadsheet
Enable Sheets API and OAuth at console.cloud.google.com. Common scope: https://www.googleapis.com/auth/spreadsheets. Use spreadsheets.values.batchUpdate / batchGet via SDK.

About this API
The Sheets API turns "Excel sheets" into a programmable data source. Three common patterns: (1) Sheets as backing database — non-engineers maintain data in Sheets and the app syncs via API; (2) report generation — programs write analytics output into Sheets for team consumption; (3) config hub — store feature flags, copy, and lookups in Sheets so non-engineers can change behavior without code deploys.
The API is built around batch operations: spreadsheets.values.batchUpdate modifies many ranges in one call; spreadsheets.batchUpdate executes many structural changes (insert rows, add sheets, format) in one call. Orders of magnitude faster than per-cell calls. Reads also batch via batchGet. Quotas are generous — about 60 writes and 300 reads per user per minute, plenty for normal apps. Watch the cell limit: 10M cells max per spreadsheet — large datasets need either multiple spreadsheets or a real database.

Strengths & limitations
Strengths
- Generous per-user quota
- Batch update endpoints modify many cells in one call
- Deep integration with Drive and Apps Script
Limitations
- Up to 10M cells per spreadsheet
- High-frequency writes can hit per-user quotas
- Complex formulas and pivots are awkward to construct programmatically

FAQ
Is the Sheets API free?+
Yes, free with per-user quotas that are very hard for normal apps to exhaust.
Can I read someone else's sheet without user OAuth?+
Share the sheet with a service account (as a collaborator); the service account can then access it. Workspace customers can also use domain-wide delegation.
Why are my writes slow?+
Per-cell writes are slow. Use batchUpdate to merge many cells into one request — typically 10–100x faster.
