Can I Undo Changes After a Bulksheet Upload?
← Back to How to Update Amazon Sponsored Products Bids With a Bulksheet
Quick answer
Amazon bulksheet upload mistakes can be reversed by re-uploading a backup copy of the original spreadsheet values. This applies to bid changes, match type edits, status updates, and negative keyword assignments made through Amazon Sponsored Products bulk files. The safest approach is to keep an unchanged copy of the previous bulksheet before applying a new upload, so previous values can be restored row by row.
A rollback usually does not require an undo button inside the Amazon interface. Instead, the fix is a new bulksheet upload that puts the original values back. The important part is that you saved those values before the mistake happened or before you made large-scale edits.
Save a clean backup before every upload
Bulk edits can touch hundreds or thousands of rows at once. If you do not have the last-known-good version of the file, reversing a mistake may mean rebuilding bids from the Amazon Ads console or from campaign reports.
- Download the current campaign data and keep the file separate.
- Make changes in a copy, not the original file.
- Before uploading, save a timestamped backup of both the pre-edit and post-edit versions.
- Store backups until you confirm the upload processed correctly.
Revert using the backup file
To undo an upload, open the backup file that contains the previous values and re-upload it with the same entity IDs and targeting rows. The goal is to restore the exact bid, status, or negative keyword value that existed before the mistake.
- Identify the rows affected by the bad upload.
- Copy those original values from the backup bulksheet.
- Upload the correction file and check the processing report for errors.
- Wait for the changes to reflect in Amazon Ads before making additional edits.
If you manage multiple accounts, a read-only view like the Amazon Ads Dashboard by Todoza can help you verify performance after a rollback without making accidental live changes.
When this matters
Rollback risk increases when a single bulksheet contains many campaigns, ad groups, and match types. A small formatting error can apply the wrong bid to a high-spend keyword or move a negative keyword to a shared negative list.
In those cases, returning to the previous values quickly limits wasted spend. It also helps to use tools that flag waste without changing campaigns automatically. The Amazon Negative Keyword Tool by Todoza is read-only and can identify negative keyword candidates before you add them to a bulksheet.
