Product Spec Extractor for Sellers

WHAT IT DOES

Product Spec Extractor for Sellers is a browser extension that automatically scans the current webpage for product specifications, technical details, attribute tables, feature lists, and product description sections. It detects spec-related elements by examining class names, IDs, data attributes, and text patterns for keywords like "spec", "attribute", "feature", "detail", "technical", or "specification". The extension adds a floating "extract spec" button (⚙️) next to each detected spec element, allowing you to select individual spec items for bulk export, capture product name, attribute name, attribute value, and custom notes. Clicking the button toggles the selection state, and selected specs are added to a bulk collection. The main panel allows you to export all selected product specifications in three formats: CSV (with product, attribute, and value columns), JSON (structured data), or formatted text (attribute-value pairs). The panel also displays saved spec history with attribute names, values, product names, notes, and tags. The extension maintains a product spec database per product and attribute with export history, notes, and tags for each tracked spec. All data is stored locally in your browser using GM_setValue, ensuring your spec collections persist across page reloads and browser sessions. This helps e-commerce sellers, catalog managers, product researchers, and anyone who needs to extract and track product specifications for listing creation, product comparison, catalog management, or competitive analysis.

WHERE IT RUNS

This extension runs on any webpage that displays product specifications, technical details, attribute tables, feature lists, or product description sections – including e-commerce product pages, manufacturer websites, catalog databases, comparison shopping sites, and any page containing product specification data. The extension intelligently adapts to different page structures and supports a wide range of common spec display patterns, including HTML tables, definition lists, and feature grids. No manual configuration is required per site; the extension automatically detects spec elements using a flexible pattern matching system. This makes it ideal for sellers, product researchers, and catalog managers who need to extract spec data for listings and analysis.

HOW TO USE

Simply install the extension and navigate to any webpage displaying product specifications. The extension automatically detects spec elements and places a small "extract spec" button (⚙️) next to each one. Click any of these buttons to select that spec item for bulk export – the button highlights to show it's selected. Click it again to deselect. As you select specs, a counter at the bottom-right shows how many you've collected. When ready, click the floating button (📐) to open the main panel. Choose your preferred output format (CSV, JSON, or formatted text), then click "Export Selected Specs" to copy all collected product specifications to your clipboard in the selected format. The panel also displays your saved spec history for reference. Add notes about spec accuracy, missing attributes, data sources, or any other relevant detail when saving spec information. Use the settings section to enable or disable auto-detection and set your preferred default export format. The "Clear All Specs" button removes all tracking data when needed.

ONE TECHNICAL SECTION – WHY IT WORKS

The extension employs a multi-layered detection system that identifies product specifications with high accuracy. First, it scans the DOM using a comprehensive set of CSS selectors targeting common spec-related class patterns, IDs, and data attributes like "spec", "attribute", "feature", "detail", "technical", and table elements. Second, it examines table rows and list items to extract attribute-value pairs from structured data. The product name extraction identifies product titles from text patterns and data attributes. The attribute name extraction identifies spec labels from table headers, list items, and data attributes. The attribute value extraction identifies corresponding values from the same elements. Each tracked spec is assigned a unique ID based on the product name and attribute name, ensuring that history stays correctly associated even when the same spec appears in different contexts. The extension handles multiple spec formats including HTML tables, definition lists (dt/dd), and unordered lists of key-value pairs. A MutationObserver detects dynamic content updates and re-scans only when new spec elements appear, balancing real-time accuracy with system performance.

THE PANEL – DRAG / PER-SITE POSITION / SNAP / COLLAPSE / RESIZE / ESCAPE

The product spec extraction panel includes a draggable title bar, allowing you to position it anywhere on screen for convenient access during product research. The extension remembers your preferred position per website, so the panel opens in the same location each time you return to that domain. The panel supports snap-to-edge behavior – when dragged near screen edges, it gently snaps into place for a tidy workspace layout. You can collapse the panel down to just its title bar by clicking the collapse button, keeping it accessible without taking up screen space. The spec list and history are contained within a scrollable body, ensuring all content remains accessible even on smaller screens. Pressing the Escape key closes the panel instantly, returning you to your product research workflow.

PLEASE NOTE

This extension requires the free BotGentz extension to be installed and enabled, as it relies on BotGentz's userscript injection and GM_* API shims for cross-browser compatibility. Websites frequently update their HTML structures and class names, which may cause spec detection to break temporarily – we actively maintain the matching patterns and release updates regularly. The extension stores all product spec data, export history, and notes exclusively in your local browser storage (GM_setValue); no data is ever transmitted to any external server or third party. You are responsible for backing up your spec tracking data if you switch browsers or clear your storage. The extension does not read, modify, or interfere with any product data, listings, or site functionality – it operates solely on the static page content and stores only metadata (product names, attribute names, attribute values, and notes) that you explicitly create. Use this tool responsibly for internal product research and catalog management purposes.
