dataslayer Extension

dataslayer adds a panel to Chrome Developer Tools that monitors tag management data layers and displays changes in an easy-to-read, user-friendly format.

Supported TMS/variables include:
- Google Tag Manager dataLayer variable
- Adobe Launch rules and data elements
- Adobe DTM page load rules and detection
- Tealium data layer
- TagCommander data layer
- custom data layers (any variable represented as a JavaScript object)

dataslayer supports multiple data layers / GTM containers on a single page, including those in embedded iframes.

dataslayer also decodes and displays tags (including pageviews, variables, and click events) from:
- Google Analytics (including App + Web, Universal Analytics / analytics.js, dc.js, and ga.js)
- Adobe Analytics / Omniture SiteCatalyst
- Floodlight

If you're using a beta or dev channel of Chrome, you can optionally enable blocking of captured tags to prevent data pollution.

For feature requests and bug reports, please either use the 'Send Feedback' option in the Chrome Web Store or reach out directly to [email protected].

Bogdan Nazaruk (ID: 0000004c1e160ab5) Voted 5 ★ - Updated 03/28/2022 The interface is really awkward. It would be nice to rework how the data is presented. Becomes hard to work with. But the backend is amazing. Just looked through the source to see how it gets all DEs. _satellite._container.dataElements Pretty cool. Didn't realize _satellite gave access to all DEs.
