Why teams connect Google Cloud Spanner and Google Sheets

Mirror Google Sheets's data into Google Cloud Spanner so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Google Sheets through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Google Cloud Spanner.

Stacksync mirrors Sheets (tabs), Rows, Ranges, Named ranges from Google Sheets into Change streams, Views, Databases, Tables in Google Cloud Spanner and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Google Sheets, so the tool and the database never disagree.

Common use cases

  • Reconcile finance or billing exports against system-of-record data in one collaborative surface.
  • Prototype an integration by syncing a sheet before committing to a database schema.
  • Push billing or entitlement changes from finance tools into Spanner tables the application reads at runtime.
  • Use change streams to feed near-real-time copies of operational tables into an analytics warehouse.

Read Google Sheets with a query

Records from Google Sheets are ordinary rows in Google Cloud Spanner; join them, index them, and use them in application logic without touching the vendor API.

Automate Google Sheets from your codebase

Write to the synced tables in Google Cloud Spanner and Stacksync propagates the change into Google Sheets, replacing custom integration code.

React to changes as they happen

Updates in Google Sheets arrive as row changes in Google Cloud Spanner, so triggers, jobs, and services can respond in near real time.

What you can sync between Google Cloud Spanner and Google Sheets

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Google Cloud Spanner objects Google Sheets objects
Tables Relational tables mapped one-to-one to sync targets. Spreadsheets The file-level container a sync connects to, identified by spreadsheet ID.
Rows The unit of read and write in each sync cycle, keyed by primary key. Sheets (tabs) Individual worksheets, typically mapped one-to-one to a synced table.
Interleaved tables Child rows physically co-located with parents; synced as related records. Rows Treated as records; a header row usually defines field names.
Secondary indexes Used to make incremental read queries efficient on non-key columns. Ranges Addressed in A1 notation for batched reads and writes.
Change streams Capture inserts, updates, and deletes for log-style change data capture. Named ranges Stable references that keep sync mappings valid when the grid moves.
Views Read-only projections useful for shaping data before it leaves Spanner. Cell values Untyped by default, so syncs handle type coercion for dates and numbers.

How the Google Cloud Spanner and Google Sheets connectors work

Google Cloud Spanner

Integration surface
gRPC/REST client API with SQL query surface (GoogleSQL and PostgreSQL-interface dialects)
Authentication
Google Cloud IAM (service accounts)
Change detection
Change streams (log-style CDC), or timestamp-based polling queries
Capabilities
read · write · CDC
Rate limits
Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.

Google Sheets

Integration surface
REST API (Google Sheets API), with file-level change signals available through the Drive API
Authentication
OAuth 2.0 (user consent) or Google service accounts
Change detection
Polling; the Sheets API has no cell-level webhooks, and Drive push notifications only signal file-level changes
Capabilities
read · write
Rate limits
Subject to per-minute read and write quotas per project and per user, so large syncs are batched.
