CartMatrix: Product & Pricing Matrix Extractor

Turn any online store into a sortable pricing matrix: products, prices, variants and stock. Export CSV or JSON. Runs 100% locally.

CartMatrix turns the store page you're looking at into a clean, sortable pricing matrix of products, prices, sale discounts, variants and stock. Export it to CSV in one click. Everything runs inside your browser: no account, no server, no tracking. WHAT IT DOES • Finds the products on the page you're viewing: Shopify and WooCommerce stores, marketplace search and product pages, and many other online shops. CartMatrix reads product cards, structured data and the data stores publish for their own pages. • Price summary at a glance: item count, median price, how many items are on sale and sold out, plus a price-distribution histogram. • Sortable matrix with thumbnails, price, compare-at price, discount %, stock and vendor. Filter by name, SKU or vendor. • Hover-to-locate: hover a row and the matching product on the page lights up with an outline. Click the row to scroll to it. • Live re-scan: products added by infinite scroll or "Load more" join the matrix automatically, with a "+N new" counter. • Toolbar badge: shows how many products CartMatrix found on the current tab. • CSV export: UTF-8 with a byte-order mark so Excel opens it correctly, and protected against spreadsheet formula injection. CARTMATRIX PRO: one-time purchase, $9.99 lifetime • Full-catalog scan: every product and variant in a Shopify store, not just the ones on screen. • One row per variant, with SKU, price, compare-at price and stock. • JSON export, and one-click copy for Google Sheets and Excel. • Column picker for the matrix and every export. The free features need no license. Pro is sold through Gumroad, and each license key works on up to 3 devices. WHO IT'S FOR • Store owners and merchandisers reviewing a catalog's prices and stock • Analysts and agencies doing competitor price research • Resellers and shoppers comparing deals across a collection 100% LOCAL, PRIVATE BY DESIGN CartMatrix reads product information from the page inside your browser and keeps it in that tab's memory until you close the tab. It has no server and sends nothing to the developer. It makes only two kinds of request on its own: the optional full-catalog scan, sent to the store you're viewing, and a license check with Gumroad when you activate a purchased key. No analytics, no ads, no remote code. PERMISSIONS, AND WHY • Read site data on all websites: online stores live on every kind of domain, so CartMatrix checks each page you open for product listings. Pages without products are left alone, and nothing is sent anywhere. • Storage: saves your settings and license status. • Clipboard (write only): the "Sheets" button copies the table for pasting into a spreadsheet. CartMatrix never reads your clipboard.
