Description
Scrape product listings and detail pages from Mercari US. Select categories, scrape current pages, and export to CSV. Mercari Scraper is a Chrome extension that automatically collects product listings from Mercari US (www.mercari.com/us/) and saves them as a CSV — or JSON — file you can open in Excel or Google Sheets. It works entirely inside your browser. No accounts, no API keys, no third-party servers — your data stays on your computer. What you can collect per item Each scraped listing includes: Title, Price, Currency, Condition, Brand, Description, Category, Image URL, All Images, Item URL, Item ID, Seller Name, Seller Username, Seller Rating, Seller Reviews, Seller Listed, Seller Sales, Seller Verified, Seller Logo, Seller Profile Link, Shipping Payer, Return Policy, Size, Color, Posted Date, Delivery From, Delivery Shipping, Delivery Payments, and more. Two scrape modes Current Page — Scrapes whatever Mercari page is open in your active tab: search results, a seller's profile, a collection, or any listing grid. Auto-scroll loads more products as you scroll down. Works with "View More" buttons too. Scrape Category (Pro) — Select one or more categories from Mercari's full navigation tree (T1 → T2 → T3). The scraper visits each category URL automatically, scrolls through all listings, and collects item data — then moves to the next category. How it works Open Mercari US in Chrome and click the extension icon. Choose a scrape mode and adjust settings. Click Start — the scraper opens a background tab, extracts visible items, scrolls to load more, and repeats until it reaches the page end. (Pro) Enable detail page scraping to open each listing in its own tab and collect 30+ fields including full description, seller profile, shipping, and all images. Click Export CSV or Export JSON to download all collected data. Pro features Unlimited items (Free: up to 500) Detail page enrichment — 30+ fields per item Filters — by status (on sale / sold), price range, and condition Scrape Category mode — full category tree navigation Image download — saves product images to disk Clean CSV export without Free watermark
