Every bullet point has a strict 500-character limit. When even one bullet point exceeds it, Amazon silently blocks your entire flat file upload or suppresses the listing. With 100+ ASINs and 5 bullet fields each, manually finding the violations is impossible.
Amazon blocks your entire flat file upload — even one bad bullet can stop hundreds of updates.
Violations can cause Amazon to suppress your listing, costing you visibility and sales.
Seller Central doesn't tell you which ASIN or which bullet caused the problem.
Drag and drop your Amazon Seller Central flat file (CSV or TXT) directly into the tool. Nothing is uploaded to any server.
The tool checks every bullet_point1 through bullet_point5 field for every ASIN against your configured character limit.

Amazon enforces a 500-character limit per bullet point for most seller categories. Only the first 1,000 bytes across all 5 bullet fields are indexed for search. Exceeding the per-bullet limit can cause your entire flat file upload to be rejected.
Amazon validates all bullet_point fields during flat file processing. If any single bullet point exceeds your category's character limit, Amazon may reject the entire upload — without clearly identifying which ASIN or which field caused the problem.
