Export a list of your network's ad units to a spreadsheet, by following the steps below:
- Sign in to Google Ad Manager.
- Click Inventory Ad units.
- (optional) Click Add new filter to narrow down the results by ad unit hierarchy, size, status, and more.
- Click Download.
A spreadsheet in CSV format is automatically downloaded, containing the ad units being filtered. If you don't apply any filters, the spreadsheet will contain all un-archived ad units.
The downloaded spreadsheet can contain up to 20,000 ad units. If your network's count of ad units exceeds this limit, the downloaded file will contain as many as possible, but not a full list of your network's ad units. Use filters to reduce the number of exported ad units.
