GTM container health check.
Deep dive into the health of your Google Tag Manager setup. Upload your exported container JSON and discover issues, cleanup opportunities, and legacy tags in seconds — no access to your GTM account required.
Step-by-step guide
Export your container
In Google Tag Manager, go to Admin, then select “Export Container” from the Container column. Choose a version and download the JSON file.
Upload and review
Drag the exported JSON into the tool. You'll get a container health score along with a breakdown of issues, cleanup opportunities, and legacy tags worth removing.
Containers drift. Tags pile up through team changes, agency handoffs, and quick fixes that never get revisited. Run a health check quarterly — or any time ownership of your measurement changes hands.
