LeoMeasure DataLayer Checker is a powerful Chrome Extension for GTM dataLayer preview real time. It helps you preview and debug dataLayer events and data without relying on GTM’s built-in preview mode or the browser console for Shopify Custom Pixel.
Key Features:
DataLayer Checker: Easily preview and debug the dataLayer on any website — even when GTM's native preview mode is not available.
Copy DataLayer Path: Instantly copy the path of any object inside the dataLayer to create GTM variables quickly and accurately in Google Tag Manager.
DataLayer Checker for Shopify Custom Pixel: Shopify Custom Pixel events don’t appear in GTM preview mode by default. This extension lets you view those dataLayer events directly, without opening the browser console.
Simulate GTM Preview for Shopify: Enable GTM-like preview behavior for Shopify Custom Pixel integrations with a single toggle.
