Extract Product Info from Webpage Screenshots using Dumpling AI & GPT-4o

This n8n workflow monitors a Google Sheet for new product webpage URLs. Upon detecting a new entry, it captures a full-page screenshot using Dumpling AI, saves it to Google Drive, extracts text via OCR with Dumpling AI, and processes the text with GPT-4o to identify and structure product details like name, price, ratings, deals, and purchase options.

The GPT-4o output, formatted as an array of product objects, is split into individual items and appended to a dedicated Google Sheet for easy analysis. This approach overcomes limitations of traditional web scraping on dynamic or protected sites, ensuring reliable data collection without coding.

Ideal for eCommerce teams tracking competitors, market researchers compiling product catalogs, and virtual assistants performing comparisons. Benefits include full automation, high accuracy from AI vision models, scalable processing, and integration with familiar Google tools—saving hours of manual data entry weekly.
