You can bulk-upload translated ad copy in Microsoft Advertising Editor without overwriting tracking templates by using a controlled export-edit-import workflow and limiting your upload to the fields that need translation.
The safest approach is to update existing ads rather than recreate them, preserve their IDs and tracking settings, and avoid including tracking-template columns in the import unless you intentionally want to change them.
Recommended workflow
1. Download a backup: Sync your Microsoft Advertising account in Editor and export the existing campaigns and ads before making changes.
2. Separate translations by language: Organise translated headlines and descriptions by campaign, ad group, and target language. Keep the corresponding final URLs aligned with each language's landing page.
3. Update existing ads: Use the existing ad IDs when updating ads. This helps ensure you edit the intended entities instead of accidentally creating duplicates.
4. Exclude tracking fields: Do not include Tracking Template, Final URL Suffix, or custom URL parameter fields in your translation upload if you do not intend to modify them. Microsoft supports selective bulk updates, so you can retain only the fields needed for your changes.
5. Validate before publishing: Review the imported changes and confirm that only the intended ad copy fields have changed. Check that tracking templates, final URLs, custom parameters, and campaign settings remain intact.
6. Test before scaling: Upload changes for one ad group first. Verify the translated ads and test their tracking URLs before applying the same process across the account.
Important safeguard
Never use blank tracking-template values as a way to preserve existing settings. Exclude those columns entirely from the update file. Also, avoid using delete_value, because Microsoft uses it to remove an existing optional field.
Microsoft's documentation explains that bulk uploads can be previewed before changes are applied. Use that preview to catch unintended updates before publishing.
My recommendation: Maintain a separate translation master sheet with columns for Campaign ID, Ad Group ID, Ad ID, Language, Headline, Description, and Final URL. Use it as your working file, then generate a selective update file for Microsoft Advertising Editor. This keeps translation management separate from tracking configuration.
