GA4 Convert - Free, Open Source Tool
It produces a clean relational data structure with strongly typed fields, suitable for querying with SQL and BI tools.
GA4 export is not "analysis-ready" by default. GA4 Convert produces tables with stable, familiar grains:
This makes it much easier to answer questions like: "What happened in this session?", "Which pages led to a form submit?", or "How many file downloads came from this landing page?"
Canonical, coerced event parameters. Event parameters are often messy: numbers arrive as strings, booleans are inconsistently represented, dates come in multiple formats, the same parameter can appear with different types across events.
The tool creates a canonical view of event parameters where values are coerced into typed columns (or NULL), and coercion failures are explicitly flagged. This gives you a reliable foundation for monitoring, learning rules later, and building consistent analysis views.
De-duplication of events. It flags likely duplicates based on a composite key.
