¿Cuál de las siguientes opciones te permite editar múltiples campañas simultáneamente con una hoja de cálculo?

Bulk Operations (Operaciones masivas) is the correct answer because this feature allows advertisers to download campaign data into a spreadsheet, make changes offline, and then upload the updated spreadsheet to apply those changes across multiple campaigns simultaneously. This is highly efficient for managing large accounts. The API (Application Programming Interface) is a programmatic interface for interacting with the advertising platform, but it requires coding knowledge and is not a direct spreadsheet-based editing tool for most users. "Both" and "None of the above" are incorrect because Bulk Operations specifically addresses the scenario of editing multiple campaigns with a spreadsheet.
