If you can't bulk import updates to your existing ads in Ads Manager:

• Make sure that all the columns from the original Ads Manager Excel template are there
• Make sure that you don't delete the ad IDs, as you're editing ads and not creating new ones.
• Save the Excel file as a Unicode .txt file.
• Click Export & import in Ads Manager and select Import ads in bulk to import your Excel template back to Ads Manager.

If you still can't import updates to your existing ads in Ads Manager, file a task by clicking Help on the top right-hand side of Ads Manager and select Report a problem. In the task, include your account ID, .xls or .csv file that you're trying to import (not a .txt file) and, if possible, a video screencast.
