When you prepare a CSV file for importing in Google Ads Editor, include an "Ad schedule" column to add, change, or remove ad schedules. The ad schedule changes should appear on the same row as the campaign name or sitelink that you want to edit. See a sample CSV file.
| "Ad schedule" column value | Result |
|---|---|
| (Day[time-time]) | Enable the specified ad schedule. See formatting instructions. |
| [ ] | Remove existing ad schedules. |
| Leave column blank. | No changes. |
