Reverse ETL

ELT vs. reverse ETL: Excel and Amazon Redshift Cluster

ELT (Extract, Load, Transform) moves data from Excel into Amazon Redshift Cluster 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 Amazon Redshift Cluster back into Excel. For example, you could sync computed lead scores or customer segments from your warehouse into Excel to personalize outreach.

Weld supports both directions, so you can build a complete data loop between Excel and Amazon Redshift Cluster.

Amazon Redshift Cluster to Excel
Incremental syncing
Weld uses incremental syncing where supported by the Excel API, loading only new and updated records to minimize data transfer and warehouse costs.
Schema handling
Weld automatically manages schema changes. If Excel adds new fields, they're detected and added to the corresponding Amazon Redshift Cluster 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.
