Create new ads in Excel by exporting existing ads, adding new ads as new rows and then importing your spreadsheet back to Ads Manager

1. Select ads or campaigns from the Ads or Campaigns view in the main pane, click Export & import, and select Export selected. An Excel file will download.
2. Open and save the downloaded file on your hard drive before adding new ads. This file will show you data about the ads that you selected, or all of the ads belonging to the campaigns that you selected.
3. Add a new row in the spreadsheet and fill in each column except for the Ad ID for each new ad that you want to create. If you want to create new ads within a new campaign, you should also leave the Campaign ID and Campaign name blank. Save the file.
4. Click Export & import in Ads Manager, and select Import ads in bulk. You can also copy the spreadsheet using Ctrl+C or Command+C, click in Ads Manager, select Import → Paste into text area, then paste using Ctrl+V or Command+V.
5. Using the Image upload functionality of the Import ads in bulk button, add your pictures one by one or by uploading a zip file. Please make sure that your pictures' names match the names that you entered in your Excel spreadsheet in the Image column.
