The Scale Problem

Why Individual Checking Doesn't Work at Scale

The number of bullet fields that need checking grows quickly with catalog size.

Who This Is For

Built for Large Catalog Volume and Agency Workflows

The smaller your catalog, the less you need this. The larger it is, the more it becomes indispensable.

Private label brands with seasonal catalog updates

Every time you update bullet points for a range of products, run the validator before uploading. One missed violation can block the entire update — catching it first takes seconds.

Amazon listing agencies

Run bullet point validation as part of every listing project before delivery. Export the errors CSV and assign targeted fixes to your copywriting team. No client account access required — just the flat file.

Virtual assistants managing catalog maintenance

Add bullet point validation to your pre-upload checklist. Takes 30 seconds per catalog and eliminates the support burden of debugging Amazon upload rejections after the fact.

Wholesale and arbitrage sellers with large mixed catalogs

Catalog content comes from multiple suppliers with inconsistent bullet point quality. A single upload scan identifies every violation before Amazon does — regardless of where the content originated.

FAQ

Questions About Bulk Amazon Bullet Point Checking

What's the difference between the errors-only export and the full report?
The errors-only CSV contains only the rows with violations — ASIN, bullet field, character count, and overage. This is what you share with your VA or copywriter for targeted fixes. The full report includes every ASIN with character counts for all 5 bullet fields, including those within the limit — useful for catalog audits where you want a complete overview of bullet content length across all listings.
Can I run this before every flat file upload as a standard check?
Yes — and this is the recommended workflow. Add the Bullet Point Validator to your pre-upload checklist: export flat file, run validator, fix violations if any, upload. The 30-second check eliminates the possibility of bullet point violations causing rejection or suppression. One purchase covers unlimited runs with no time or usage limits.
Does the tool work with international marketplace flat files?
Yes. The tool reads any flat file exported from Amazon Seller Central regardless of marketplace. It detects bullet point column headers automatically — including international format variations. The 500-character default limit applies globally; adjust to match any marketplace-specific requirements you're aware of for your category.
