After you download your spreadsheet and enter the desired changes, upload your spreadsheet to make your bulk changes go live.
To upload your spreadsheet, go to Campaign Manager > Bulk operations and upload your file. Supported file types are .xlsx and .xls.
Monitor your upload processing in the Uploads area of the Bulk spreadsheet history section. In most cases, your file will process in less than 30 minutes; however, in some cases it can take a few hours. Once processed, your changes will apply to your campaigns.
If you receive errors or warnings, download the report and follow up on any corrections that are needed.
