# Price-Tag Parser 🤖🏷️

A Gradio web app that lets you **upload one or more retail price-tag photos** and returns:

* A structured **JSON** list of every product it can read  
* A downloadable **Excel (.xlsx)** file with the same data

The app relies on **GPT-4o-Vision** via OpenAI’s API to perform OCR + understanding in one go, guided by a strict JSON schema.
