Most Common Amazon Ads Bulksheet Errors

Invalid keywords and column format issues

Amazon is strict about what can appear in a keyword field. Keywords that contain unsupported characters, are placed in the wrong match type column, or include extra spaces or punctuation can cause the row to fail. If headers do not match the current Amazon template, the entire file may be rejected before any rows are processed.

• Use broad, phrase, and exact match values exactly as Amazon expects them.
• Keep keyword text in the correct column and avoid mixing campaign and ad group data.
• Export a fresh template from Amazon Advertising Console instead of reusing an old file.

Duplicate entries and missing mandatory fields

Duplicate rows are another common cause of bulksheet errors. When the same campaign, ad group, and keyword appears more than once, Amazon may flag a conflict or silently apply changes twice. Missing mandatory fields such as campaign name, ad group name, state, or campaign ID can also stop a row from uploading.

Before submitting, sort the file by campaign and keyword to locate duplicates. Then check the first few rows of each campaign block to confirm that required cells are filled. A short manual review usually catches most missing-field issues before upload.

When this matters: avoiding repeat errors

These errors get more disruptive when you manage multiple campaigns or marketplaces. A small formatting issue in one row can block a file that was meant to update hundreds of keywords at once. Keeping raw search term data separate from your upload file can help reduce mistakes.

For example, you can review performance in a read-only analytics view, then copy only approved changes into a clean bulksheet. Amazon Negative Keyword Tool by Todoza helps identify inefficient search terms across multiple marketplaces, so your negative keyword lists stay focused and easier to format correctly before upload.
