Marketplace Expander Tool
List Once. Sell Everywhere.
Marketplace Expander turns a single product file into upload-ready listings for Amazon, eBay and Etsy — mapped, translated and compliance-checked automatically, in minutes.
Stop rebuilding the same listing five times for five marketplaces. Upload what you have, pick where it’s going, and download a file that’s ready to import.
How it works
Three boxes. One button. The mapping is done for you.
Drop in your source
Upload your existing listing export from any marketplace and tell the tool what it is (Amazon, eBay, Etsy or generic).
Add your instructions
Tell the tool how to map and expand — currency, tone, fields to grow, anything specific. Or leave it to do the heavy lifting.
Drop in the target template
Add the empty marketplace template. It gets filled to spec and you get a download that’s ready to upload.
Everything packed into one tool
Automatic field mapping
Source columns are matched to the target’s exact headers, order and delimiter — no manual copy-paste, no broken imports.
Marketplace presets
Tag the source and target as Amazon, eBay or Etsy so the tool follows each platform’s field conventions and limits.
10+ language translation
Translate titles, bullets, descriptions and keywords while leaving SKUs, barcodes, prices and headers untouched.
Legality & compliance scan
Choose a target country and get a flagged pre-check: restricted claims, labelling, policy risks and missing info.
eBay HTML descriptions
One tick builds a premium, mobile-friendly HTML description — styled to eBay’s rules, no banned active content.
Built-in upload guides
Step-by-step download & upload instructions for Amazon, eBay and Etsy, with the official links, right on the page.
One listing. Every market’s language.
Selling into Germany, France, Spain or beyond means rewriting every title and description in-language. Marketplace Expander does it in the same pass it maps your file — translating only the customer-facing copy and protecting the data that has to stay exactly as it is.
Your identifiers, prices and column headers are never touched, so the translated file still imports cleanly.
Catch problems before the marketplace does.
Pick the country you’re selling into and Marketplace Expander runs an automatic pre-check on your listing — flagging restricted or risky claims, local labelling and regulatory requirements, marketplace policy issues, and missing mandatory fields, each rated by severity.
It’s an automated pre-check to surface issues early — not a substitute for verifying against official policy and current regulations.
High-end eBay descriptions, generated for you.
Tick one box and a polished, structured HTML description is built from your product data — header, feature list, specifications table and all — using clean inline styling that renders beautifully on desktop and mobile.
No JavaScript, forms or external assets, so it stays inside eBay’s active-content rules and won’t get stripped at upload.
Made for sellers who are scaling
Multi-channel sellers
Already on one marketplace and want to be on three — without tripling your listing workload.
Cross-border brands
Expanding into new countries and need listings in-language and on the right side of local rules.
Busy operators
Anyone tired of reformatting the same product data by hand, file after file, channel after channel.
Questions, answered
Which file types does it handle?
CSV, XML and TXT, both as your source export and as the target marketplace template.
Which marketplaces are supported?
Presets for Amazon, eBay and Etsy, plus a generic mode for any platform whose template you can supply. Built-in guides show you exactly where to download and upload each one.
Does translation break my data?
No. It translates only the customer-facing copy — titles, bullets, descriptions and keywords — and deliberately leaves SKUs, barcodes, identifiers, prices and column headers exactly as they are.
Is the compliance scan legal advice?
No — it’s an automated pre-check to surface potential issues early so nothing obvious slips through. Always confirm against official marketplace policy and current regulations before you list.
