How StriveFormats detects this

StriveFormats parses every row of your CSV and applies Amazon-specific validation rules to the Invalid product-id field. Any row that violates the rule is flagged with the row number and the specific value that caused the issue.

►Technical detail
Amazon's importer validates the Invalid product-id field against its official import specification. Values that do not meet the expected format are flagged to prevent silent data corruption -- an invalid value that slips through import might appear as a blank field, a zero, or incorrect text in your storefront without any error message after the fact.
