How do I sync Google Sheets data to Apache Iceberg?

Sign up for Weld, connect Google Sheets as a source and Apache Iceberg as a destination. Weld handles the extraction, loading, and lets you transform data using SQL or dbt.

What Google Sheets data can I sync to Apache Iceberg?

You can sync Worksheets, Rows, and Named Ranges. The available objects depend on your Google Sheets account permissions and configuration.

How often does Weld sync data from Google Sheets?

Sync frequency depends on your Weld plan. Schedules range from every 5 minutes to daily intervals. Each sync processes only new and changed data.

Can I transform Google Sheets data before it lands in Apache Iceberg?

Yes. Weld supports SQL-based transformations in the platform and integrates with dbt Cloud. You can clean, join, and model your data before analysis.

Is the Google Sheets to Apache Iceberg integration secure?

Yes. Weld encrypts all data in transit and at rest, is SOC 2 Type II certified, and supports IP whitelisting. Credentials are stored encrypted and never logged.

Can I also sync data from Apache Iceberg to Google Sheets?

Yes. Weld supports both directions. You can use reverse ETL to push data back into Google Sheets.

Reverse ETL

ELT vs. reverse ETL: Google Sheets and Apache Iceberg

ELT (Extract, Load, Transform) moves data from Google Sheets into Apache Iceberg for analysis. This is the approach shown on this page, and the one to use for dashboards, reports, and data models.

Reverse ETL works the other direction: it pushes enriched data from Apache Iceberg back into Google Sheets. For example, you could sync computed lead scores or customer segments from your warehouse into Google Sheets to personalize outreach.

Weld supports both directions, so you can build a complete data loop between Google Sheets and Apache Iceberg.

Apache Iceberg to Google Sheets

Incremental syncing: Weld uses incremental syncing where supported by the Google Sheets API, loading only new and updated records to minimize data transfer and warehouse costs.
Schema handling: Weld automatically manages schema changes. If Google Sheets adds new fields, they're detected and added to the corresponding Apache Iceberg tables.
Data freshness: Sync frequency depends on your Weld plan. Most connectors support schedules from every 5 minutes up to daily intervals.
Security: All data is encrypted in transit (TLS) and at rest. Weld is SOC 2 Type II compliant and supports IP whitelisting for database connections.
