Upload Only the Necessary Columns in Your Bulksheet
← Back to How to Create Amazon Sponsored Products Campaigns With a Bulksheet
Quick answer
Amazon Sponsored Products bulksheets are spreadsheet files that let you create or edit multiple campaigns at once. Uploading only the necessary columns is a simple way to improve file reliability. Many templates include optional fields for advanced settings, but most basic campaign builds only need a limited set of identifiers, targeting values, and bid information. Keeping unused columns out of the upload reduces errors, makes the file easier to review, and helps Amazon process the bulksheet more cleanly.
If you have ever opened a bulksheet template and felt overwhelmed by the number of columns, you are not alone. The good news is that many of those columns are optional, and a focused file is often easier to troubleshoot.
Why Fewer Columns Reduces Upload Errors
Amazon bulksheets can include a large number of optional columns for different campaign types and advanced settings. When unused columns stay in the file, leftover values, formatting inconsistencies, or hidden characters can trigger processing errors. Deleting empty or irrelevant columns keeps the upload lean and makes it easier to catch mistakes before you submit the file. It also reduces the chance that an old value in an optional field overrides your intended settings.
Which Columns to Keep for a Basic Sponsored Products Upload
A lean Sponsored Products bulksheet usually focuses on the identifiers and bid settings needed to create a campaign. Common columns to keep include:
- Campaign name and ad group name
- SKU or ASIN
- Keyword or product targeting expression
- Match type
- Bid
- Status
If you are not using placement modifiers, campaign-level bidding strategies, or other advanced controls, those columns can often be deleted from the working file rather than left blank. Before making changes, save a copy of the original template so you can restore any columns if an upload requires them.
When This Matters Most
Trimming columns is especially useful when you are managing multiple campaigns or refreshing an existing bulksheet. A lean file is easier to audit before upload, and it pairs well with post-upload performance review. After your campaigns go live, you can use the Amazon Ads Dashboard by Todoza to monitor spend and performance trends across accounts without adding extra columns to your next upload. Teams that keep working files focused typically spend less time troubleshooting format issues.
