Instead of creating one campaign at a time, you can use bulksheets to define and modify multiple manual campaigns and upload them all at the same time.
Shopping campaigns can’t be created from a bulksheet, but you can use a bulksheet to manage product groups.
Start with the basics
If you're new to bulksheets, it's usually best to keep your uploads basic. For example, for your first upload you might try creating a single campaign in a single client account. Then as you grow familiar with the process, you can use more advanced functionality all the way up to uploading multiple campaigns, ad groups, ads, and keywords in different types of client accounts.
No IDs required to create items
Search Ads 360 generates a unique numeric ID for each client account, campaign, ad group, ad, keyword, and other items that you create. You can view these IDs by adding the ID column to a statistics table. IDs are always included when you download an editable report.
When you're creating new campaigns, ad groups, ads, or keywords, you don't need to specify the numeric ID of the parent accounts, campaigns, and ad groups, respectively. Instead, you can refer to the parent account by the names you specified when you created the parent accounts.
