Preview GTM dataLayer, debug with GTM inject, and fix Shopify Custom Pixel preview issues.

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.
