Extract auction and marketplace listings, prices, seller info and product data. Export to CSV, JSON, Excel. You need auction and marketplace listing data. But getting it out is painful. Copying titles, prices, and seller details one by one. Scrolling through hundreds of search results. Clicking into each listing just to grab shipping costs and condition info. If you've ever tried to collect marketplace data at scale, you know the drill - hours of repetitive clicking for a dataset that should take minutes. AuctionData Scraper fixes this. One extension, all the public data you need, exported in seconds. WHY COLLECTING AUCTION DATA IS SO HARD Online auction platforms don't offer a public data export. There's no "download all listings" button. That leaves resellers, researchers, and collectors stuck with two options: manual copy-paste or expensive third-party tools. - Listing details are scattered across search results, category pages, and seller stores - Pricing, shipping costs, and item conditions require clicking into each listing - Bid history and seller ratings are buried behind multiple clicks - There's no native way to compare prices across multiple searches or regions Most people end up with incomplete spreadsheets and wasted afternoons. This extension solves that by intercepting the data already loaded in your browser and letting you export it cleanly. WHAT THIS EXTENSION DOES AuctionData Scraper runs entirely in your browser. It captures public listing data as pages load - no external servers, no API keys, no accounts required. Just navigate to any supported page and start collecting. No spreadsheet formulas. No manual copying. No third-party data brokers. Here's what you can extract: Listings - Captures titles, prices, bid counts, shipping costs, item conditions, seller names, seller ratings, listing formats (auction/buy-it-now), time remaining, and thumbnail images. Works on search results, category pages, and seller stores. Product Details - Full metadata from individual listing pages including descriptions, specifications, item specifics, shipping options, return policies, and payment methods. Seller Profiles - Seller names, feedback scores, positive feedback percentages, registration dates, and store information. Sold Items - Completed listings with final prices, sale dates, and buyer counts for price research. HOW IT WORKS 1. Install the extension and navigate to any supported marketplace page 2. Click the extension icon to open the scraper panel 3. Select what data you want to collect (listings, details, sellers, or sold items) 4. Choose your fields - customize exactly which data points to capture 5. Hit scrape - the extension collects data as you scroll or auto-paginates for you 6. Export to your preferred format That's it. Most extractions finish in under a minute. MONITORING AND ALERTS Page Watcher lets you track changes on any page and get notified instantly. Set conditions on specific fields - price drops, new listings, auction endings - and receive alerts via webhook or ntfy.sh when those conditions are met. Schedule regular checks to stay on top of deals. Perfect for tracking price trends, sniping deals, or monitoring competitor listings. BATCH PROCESSING Batch URL Opener lets you queue multiple URLs and process them all in one session. Add URLs manually or auto-collect them from search results, then batch-process and export all results together. Ideal for collecting data across dozens of listings or seller stores without clicking through each one individually. EXPORT FORMATS - CSV - Open in Excel, Google Sheets, or any spreadsheet tool - Excel (XLSX) - Native Excel format with proper formatting - JSON - Structured data for developers and automation pipelines - HTML Table - Quick visual preview in any browser - Raw JSON - Unprocessed API response data for advanced users Choose the format that fits your workflow.
