Why teams connect Smartsheet and Snowflake

Get the data locked inside Smartsheet into Snowflake as live tables, and send results back where Smartsheet can use them, without writing a pipeline.

Whatever Smartsheet is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Reports, Attachments, Discussions and Comments, Users and Groups from Smartsheet into tables in Snowflake continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Snowflake can also be written back into fields in Smartsheet where the tool can use them.

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 Keep a customer 360 table aligned with its source systems in both directions instead of one-way reverse ETL
  • 04 Push product usage aggregates from Snowflake into sales and success tools for account prioritization

Common sync patterns

History that outlives the tool

A continuously synced copy in Snowflake preserves a queryable record even as data ages out of Smartsheet or gets changed inside it.

Analytics on Smartsheet's data

Records and events from Smartsheet land in Snowflake as queryable tables, current within seconds and ready to join with the rest of the warehouse.

Cross-tool reporting

Combine Smartsheet's data with data from every other synced system to answer questions no single tool can.

What you can sync between Smartsheet and Snowflake

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.

Smartsheet objects Snowflake objects How this pairing syncs
Attachments Files linked to rows or sheets; posting one carries a 10x rate cost, so bulk file sync is throttled to 30 per minute. Tables The main landing and activation target for synced records. Attachments is specific to Smartsheet and Tables to Snowflake — each maps to any object or custom field on the other side.
Discussions and Comments Threaded comments on rows and sheets; read out to sync collaboration history or activity into another system. Views Modeled projections used as the source side of outbound syncs. Discussions and Comments is specific to Smartsheet and Views to Snowflake — each maps to any object or custom field on the other side.
Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. Materialized Views Precomputed results synced outward for low-latency reads. Users and Groups is specific to Smartsheet and Materialized Views to Snowflake — each maps to any object or custom field on the other side.
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. Streams Row-level change records on a table, consumed to process deltas instead of full scans. Sheets is specific to Smartsheet and Streams to Snowflake — each maps to any object or custom field on the other side.
Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. Stages File staging areas used for bulk loads into synced tables. Rows is specific to Smartsheet and Stages to Snowflake — each maps to any object or custom field on the other side.
Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. Tasks Scheduled SQL used to transform synced data after it lands. Columns is specific to Smartsheet and Tasks to Snowflake — each maps to any object or custom field on the other side.

How changes propagate between Smartsheet and Snowflake

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.

Smartsheet Snowflake 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 Snowflake as a row-level write, with types converted between the two schemas.

Snowflake Smartsheet Sub-second propagation

DetectionChanges in Snowflake are captured at the source via change data capture — no polling loop against its API. The setup script grants "create stream" on synced schemas (Snowflake streams), but the docs do not name the change-capture mechanism.

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

Rate-limit considerations

  • 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.
  • Snowflake: No conventional API rate limits; cost and throughput are governed by virtual warehouse size and running time.
