Why teams connect DuckDB and Smartsheet

Mirror Smartsheet's data into DuckDB 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 DuckDB.

Stacksync mirrors Users and Groups, Sheets, Rows, Columns from Smartsheet into Schemas, Tables, Views, External files (Parquet/CSV/JSON) in DuckDB 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 Mirror Users and Groups from an HR system or directory so sheet sharing and workspace access stay aligned with headcount changes.
  • 02 Trigger downstream actions in an operational database when a Row's status Cell changes, using sheet webhooks for near-real-time updates.
  • 03 Use DuckDB as a transform step: read synced Parquet exports, aggregate with SQL, and write results back to an operational database.
  • 04 Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.

Common sync patterns

Automate Smartsheet from your codebase

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

React to changes as they happen

Updates in Smartsheet arrive as row changes in DuckDB, so triggers, jobs, and services can respond in near real time.

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.

What you can sync between DuckDB 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.

DuckDB objects Smartsheet objects How this pairing syncs
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. External files (Parquet/CSV/JSON) is specific to DuckDB and Cells to Smartsheet — each maps to any object or custom field on the other side.
Attached databases Additional database files or external systems attached into one session for cross-source queries. Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. Attached databases is specific to DuckDB and Reports to Smartsheet — each maps to any object or custom field on the other side.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Attachments Files linked to rows or sheets; posting one carries a 10x rate cost, so bulk file sync is throttled to 30 per minute. Database files is specific to DuckDB and Attachments to Smartsheet — each maps to any object or custom field on the other side.
Schemas Namespaces within a database used to organize tables in sync outputs. Discussions and Comments Threaded comments on rows and sheets; read out to sync collaboration history or activity into another system. Schemas is specific to DuckDB and Discussions and Comments to Smartsheet — each maps to any object or custom field on the other side.
Tables Columnar tables created via SQL; the destination for materialized sync data. Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. Tables is specific to DuckDB and Users and Groups to Smartsheet — each maps to any object or custom field on the other side.
Views SQL views used to shape or filter data for downstream consumers. 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. Views is specific to DuckDB and Sheets to Smartsheet — each maps to any object or custom field on the other side.

How changes propagate between DuckDB 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.

DuckDB Smartsheet Interval-based propagation

DetectionStacksync polls DuckDB for changes on an incremental schedule, reading only records changed since the previous pass. Polling or full re-reads.

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

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

Rate-limit considerations

  • DuckDB: No API rate limits; throughput is bounded by local compute and I/O.
  • 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.
