GA4 Dataform is an open-source Google Cloud Dataform project that transforms GA4 raw data exports into user-friendly and modular BigQuery tables. It works by taking the raw data from GA4 and processing it to create tables that are easier to understand and use. These tables include last-click attribution models for sessions and events, and the project also allows for the development of custom attribution models.
