Find the blank fields on my US listings and fill the ones that matter. Then translate them over to my French listings.
I checked 105 US SKUs and found 1,083 values worth filling, like material, size, and care steps. I wrote French versions for the matching Amazon.fr listings too. Here are the first few:

Want to look at the rest before I send?
Looks good. Send them.
FlatFilePro checked every value first. A few sizes weren't on Amazon's allowed list, so I fixed those. All sent. I'll check back and tell you when they're live in the US and France.

01

Connect

Add FlatFilePro to Claude or ChatGPT. Sign in once. That's it.

02

Ask

"What's missing on my top sellers?" Your AI reads your real listings and tells you.

03

Fix and check

This is where FlatFilePro earns its keep. Every change runs through it on the way to Amazon.

  • Checks every value for errors before it sends
  • Tells you about any problem, then fixes it

◆ The safety net

Your AI moves fast. We make sure it doesn't break stuff.

Letting a robot edit 500 listings sounds scary. It should. That's why every change runs through FlatFilePro first.

Before anything goes to Amazon

Nothing gets sent without your OK.

Your AI shows you every change first. See it like a spreadsheet, or a few at a time. Editing tens of thousands of listings? Pick how you want to check.

Before it sends

Checks every value

We look up which values Amazon allows. Bad data gets caught and fixed before it goes.

After it sends

Proof it went live

"Accepted" is not "live." The Reflection Engine checks what shoppers actually see.

Always

Full history

Every change is saved. See who changed what, and when. Even your AI.

If you change your mind

One-click undo

Don't like a change? Roll it back. Your old listing is still there.

◆ Catalog rot

Ask what's broken. Get a straight answer.

Catalog rot is when what you sent Seller Central doesn't match what shoppers see on Amazon. 98% of listings have some.

Most sellers never find it. Now you can find it with one question, and fix it with one more.

"How do I get my UK listings translated over to Spain?"
"Did the update I sent yesterday go through?"
"Move this listing out of this variation."
"Create a new parent and move these three listings into it."
"What values does Amazon allow for this field?"
"Pull this ASIN straight from Amazon. What does it show right now?"
"Fill the blank fields on my top 20 SKUs. Show me first."
"Export every listing so I can look at it in a sheet."

  • Rather drag and drop? It's in the app too
