Listing Bench bulk EU listing editor

Runs in your browser. No account, no Amazon login, no calls out.

Family template

Bullet points
Amazon caps the generic keywords field at 250 bytes per marketplace. The counter measures bytes, not characters, so accented and non Latin terms count correctly.

Variations

Every row inherits the family template. Click a row to preview it. A row can override any field on its own without touching its siblings.

Export

One parent row plus every child, mapped to the Amazon flat file fields for the selected marketplace. In a real build these columns are matched to your exact category template, or pushed through the API. The file is generated in your browser and never leaves it.

How it would run for you least privilege by design

Fully local this sample

Edit and export a file you upload yourself. The tool never touches Seller Central and holds no credentials. Runs on your machine, offline if you want.

Read only pull

An optional scoped app that can only read your listings to pre-fill the family, nothing else. You grant it, you see exactly what it can reach.

Scoped push

If you want changes pushed back, a listings only role you approve and can revoke at any time. No blanket access, ever.

EU focus: per country text, GDPR friendly because product data stays with you and no shopper data is involved. Start local, add only the access you actually want.
