Step-by-step guide

Step 1

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.

Step 2

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.

What’s next

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.
