Why teams connect Google Cloud Spanner and Smartsheet

Mirror Smartsheet'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 Smartsheet 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 Users and Groups, Sheets, Rows, Columns from Smartsheet into Rows, Interleaved tables, Secondary indexes, Change streams 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 Smartsheet, so the tool and the database never disagree.

Common use cases

  • 01 Trigger downstream actions in an operational database when a Row's status Cell changes, using sheet webhooks for near-real-time updates.
  • 02 Two-way sync a project-tracker Sheet's Rows with a Postgres table so engineering works in SQL while project managers stay in Smartsheet.
  • 03 Run a two-way sync between Spanner and a SaaS tool so edits made by ops teams land back in the application database.
  • 04 Consolidate data from a globally distributed Spanner deployment into regional business systems.

Common sync patterns

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Smartsheet with a query

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

Automate Smartsheet from your codebase

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

What you can sync between Google Cloud Spanner and Smartsheet

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 Smartsheet objects How this pairing syncs
Rows The unit of read and write in each sync cycle, keyed by primary key. Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Secondary indexes Used to make incremental read queries efficient on non-key columns. Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. Secondary indexes is specific to Google Cloud Spanner and Reports to Smartsheet — each maps to any object or custom field on the other side.
Change streams Capture inserts, updates, and deletes for log-style change data capture. Attachments Files linked to rows or sheets; posting one carries a 10x rate cost, so bulk file sync is throttled to 30 per minute. Change streams is specific to Google Cloud Spanner and Attachments to Smartsheet — each maps to any object or custom field on the other side.
Views Read-only projections useful for shaping data before it leaves Spanner. Discussions and Comments Threaded comments on rows and sheets; read out to sync collaboration history or activity into another system. Views is specific to Google Cloud Spanner and Discussions and Comments to Smartsheet — each maps to any object or custom field on the other side.
Databases Top-level containers that scope schema and sync configuration. Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. Databases is specific to Google Cloud Spanner and Users and Groups to Smartsheet — each maps to any object or custom field on the other side.
Tables Relational tables mapped one-to-one to sync targets. Sheets The core container; each sheet has typed columns, rows, and a modifiedAt stamp. Stacksync treats a sheet as a table and syncs its rows two-way. Tables is specific to Google Cloud Spanner and Sheets to Smartsheet — each maps to any object or custom field on the other side.

How changes propagate between Google Cloud Spanner and Smartsheet

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Google Cloud Spanner Smartsheet Sub-second propagation

DetectionChanges in Google Cloud Spanner are captured at the source via change data capture — no polling loop against its API. Change streams (log-style CDC), or timestamp-based polling queries.

DeliveryEach detected change is written to Smartsheet through its API, with automatic retries and rate-limit backoff.

Smartsheet Google Cloud Spanner Sub-second propagation

DetectionSmartsheet notifies Stacksync of record changes through webhook events. Sheet-scoped webhooks subscribed to *.* events notify on row and cell changes.

DeliveryEach detected change is applied to Google Cloud Spanner as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Google Cloud Spanner: Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.
  • Smartsheet: 300 requests per minute per access token; heavy calls like posting attachments cost 10x (30/min). A 429 returns errorCode 4003, back off ~60s.
