AI eBay Listing Generator: Titles, Specifics, HTML from a Sheet
Eros C.
The problem
Writing eBay listings by hand is slow. AI can help, but sometimes it adds facts that are not true, like a release year or a card grade. A wrong fact can mean a return.
What I built
A Python tool. You upload a CSV or Excel sheet, or fill a short form. Claude writes the title (max 80 characters), the item specifics and a clean HTML description that works on a phone, with no scripts.
How it works
The AI may only use your data. After the AI, Python code checks every item specific and every number. Values that are not in your data are removed. Missing info, like the region code, is flagged instead of guessed.
Result
HTML ready to paste, a CSV for bulk upload and a review report. Test run with Claude: 6 sample products, 5 ready, 1 flagged for a missing region. 15 automated tests.

Spreadsheet in, eBay listings out. Claude writes titles, item specifics and phone-friendly HTML, and code checks that nothing is invented. Demo.
