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.

Useful extension , thank you so much.
Nice
Great tools ever.
Best tool for tracking—clean, fast, and reliable. Perfect GTM companion!
amazing
This extension is an all-in-one powerhouse for any tracking specialist. I used to rely on 'Datalayer Checker', but after its latest update introduced some bugs, I started exploring alternatives—and I'm glad I did. This tool completely won me over. It not only displays dataLayer events in a style similar to GTM's preview mode but also makes copying values seamless and efficient. With built-in features for debugging, GTM injection, and deep dataLayer inspection, it replaces multiple extensions in one clean package. If you're serious about web analytics, this extension is an absolute essential.
Extremely helpful extension within same features of all Chrome.
