Listing Scraper: Export Marketplace Items to CSV/Excel

You need marketplace listing data. But getting it out is painful. Copying prices, titles, and locations one by one into a spreadsheet. Scrolling through hundreds of results. Clicking into each listing just to grab seller details. 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. Listing Scraper fixes this. One extension, all the public listing data you need, exported in seconds. ++++++++++++++++++++++++++++++++++++++++++++++++++++ Version 1.5 - Performance & Reliability Update Fixed data extraction engine that stopped working due to Facebook platform changes. The extension now uses a more robust method to access listing data directly from the page's internal state, ensuring reliable extraction even when Facebook updates their page structure. What's fixed: - Listings extraction now works again on all Facebook Marketplace pages - Listing details, seller profiles, and seller reviews extraction restored - Improved compatibility with Facebook's latest page architecture - Added fallback mechanisms for maximum reliability Technical improvements: - Switched to React component tree traversal for data access - Added support for Facebook's normalized data store with reference resolution - Legacy extraction methods retained as automatic fallback - Better handling of dynamic field naming patterns ++++++++++++++++++++++++++++++++++++++++++++++++++++ WHY COLLECTING MARKETPLACE DATA IS SO HARD Online marketplaces don't offer a public data export. There's no "download all listings" button. That leaves resellers, researchers, and analysts stuck with two options: manual copy-paste or expensive third-party tools that charge per row. - Listing details are scattered across search results and category pages - Prices, conditions, and seller info require clicking into each item - New listings appear constantly and old ones disappear - There's no native way to compare pricing across multiple searches 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 Listing 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 marketplace 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, locations, conditions, descriptions, seller names, posting dates, and thumbnail images. Works on search results, category pages, and filtered views. Listing Details - Full metadata from individual listing pages including descriptions, seller profiles, item conditions, delivery options, and engagement metrics.
