This tool helps to identify which product and tool you are currently using to send ecommerce events to Google Analytics, how those events are interpreted by Google Analytics tags in Google Tag Manager, and how to migrate the JavaScript implementation of those events to Google's current recommendations.

1. Select whether you're using gtag.js or Google Tag Manager.
2. Enter the data for the event you want to send, as it appears in your web site's current code.
3. (Optional) Set Google Analytics 4 and Universal Analytics property IDs to send data to, if you want to see results in a Google Analytics report.
4. Press the "Submit Test" button.
5. Wait for results to appear in the result boxes.

The tool will examine the data you entered and attempt to identify whether it's using the Universal Analytics, or Google Analytics 4 data format. Additionally, it will attempt to identify which tagging solution was used.

The tool shows how the data is interpreted by Google Analytics 4 and Universal Analytics tags in GTM that have enabled reading Ecommerce data from the data layer.

This tool can assist in migration by checking that Google Analytics is receiving the same data in UA and GA4 for a given event. It can also help check that a tag is receiving the same data before and after migration.

The tool recommends how the same data can be sent to GA4 following the current GA4 documentation.

If you're migrating from ecommerce events another format, this can help understand how data in your existing events maps to the GA4 documentation.

If you're already using the gtag API and the GA4 format, you likely won't have to make any changes.
