Google Sheets as a Backend — a database-like interface for Google Sheets.

GSAB — Google Sheets as a Backend

A database-like interface for Google Sheets — schemas, validation, field encryption, async CRUD, server-side queries, and a friction-free CLI. Sign in once; no Google Cloud setup required.

Install

pip install gsab          # core
pip install "gsab[pandas]"  # + DataFrame support

Get started

gsab auth login           # browser sign-in (drive.file scope) — that's the whole setup
gsab init my-app          # scaffold a runnable starter (add --fastapi for a CRUD API)
gsab doctor --live        # prove it works end to end

Then define a schema and read/write your sheet. Full usage, examples and the API → the documentation. gsab import data.csv loads a CSV, and gsab cookbook list shows ready recipes.

Features

• Friction-free auth — gsab auth login opens a browser and uses the minimal drive.file scope. No Cloud project, no JSON keys. DIY modes cover existing sheets, your own OAuth client, gcloud, and service accounts.
• Schemas, keys & validation — typed fields, validation rules, and enforced primary_key / unique columns checked on every write.
• Field encryption — flag a field encrypted=True and it's sealed before it reaches the sheet.
• Async CRUD + upsert — insert / read / update / delete plus upsert() for idempotent insert-or-update on a primary key, with rich filters ($gt / $in / $contains / $regex and more).
• Server-side queries — query() runs the Google Visualization query language (filter, sort, aggregate) on Google's side, not in Python. Values come back type-correct.
• pandas bridge — to_dataframe() / from_dataframe() and bulk_insert() for the whole analytics ecosystem.
• Native charts — chart() embeds a Google chart in the sheet; or hand to_dataframe() to matplotlib/Plotly.
• One-call public sharing — share() publishes a created sheet to a read-only public link (and csv_url for embedding); unshare() revokes. No extra scope — GSAB owns the sheets it makes.
• Actionable errors — Google API errors become clear GSAB exceptions with retry/backoff and token refresh — readable by humans and LLM agents.
• Installable agent skills — gsab skill install drops GSAB skills into .claude/skills (or --portable for any LLM) so your coding agent knows the real API.
• Secure tokens — stored in your OS keychain (keyring), with a 0600-file fallback.

Roadmap

Shipped (v0.6.0): auth + CLI · schemas, validation & encryption · async CRUD · upsert + enforced primary keys · type-correct server-side query · pandas bridge + bulk insert · native in-sheet charts · LLM-friendly errors + retry/backoff · installable agent skills · scaffolding & CSV import (gsab init / import / doctor / cookbook) · keychain storage.

Coming next: real-time / reactive mode (polling) · rate-aware batching · MCP server (use your sheets from Claude) · terminal UI · server-side date filters · one-click hosted sign-in.
