You can manage your Microsoft Bing Ads Editor account in one language and run ads in a different language.
When you downloaded Bing Ads Editor, you selected the language option for the product. If you want to work in a different language, you'll need to download a different version of Bing Ads Editor.
Available product languages include English, French, German, Italian, Brazilian Portuguese, Spanish, and Traditional Chinese.
Your ad language setting determines the language you will use when you write your ads and should be the language of your customers.
Your ad language in combination with your location targeting determines who will see your ads. To learn more, see How does location targeting and ad language affect who can see my ads?
