Why Manually Copying Mercari Data is Costing You Time and Money
Every reseller, market researcher, and e-commerce professional knows the frustration. You find the perfect Mercari search results, then spend hours copying and pasting product titles, prices, seller information, and URLs into spreadsheets. One listing at a time. Cell by cell. Page after page.
This manual process kills productivity. It introduces errors. And it makes scaling your Mercari research virtually impossible.
Mercari Exporter solves this problem permanently.
Mercari Exporter is a Chrome extension that automatically extracts data from Mercari.com and exports it directly to CSV, Excel, JSON, XML, HTML, or TXT files. No coding required. No API keys needed. Just browse Mercari normally, and the extension captures everything in the background.
The extension works on:
Every data point Mercari displays becomes exportable in seconds.
Resellers sourcing inventory spend hours building spreadsheets of potential products. Without automation, extracting 100 listings means 100 separate copy-paste operations for titles alone. Add prices, conditions, seller info, and URLs, and you are looking at 500+ manual actions.
Mercari Exporter captures all this data automatically as you scroll. One export button gives you everything in a structured file ready for analysis.
Understanding Mercari pricing trends, popular categories, or seller strategies requires analyzing hundreds or thousands of listings. Manual collection at this scale is not just tedious, it is impractical.
The extension enables bulk data collection. Search for a product category, scroll through results, and export comprehensive datasets in minutes. Build pricing databases. Track market movements. Analyze competitor inventory. All without manual data entry.
Before purchasing from a Mercari seller, smart buyers research seller history. Manually checking ratings, review counts, sales numbers, and response times across multiple sellers wastes valuable time.
Mercari Exporter captures seller profiles instantly: join date, total sales, rating averages, review counts, verification status, and more. Compare sellers side-by-side in a spreadsheet to make informed decisions fast.
Seller reviews contain critical information about shipping speed, item accuracy, and communication quality. Reading through dozens of reviews manually gives you impressions, not data.
The extension exports review content, dates, types, feedback tags, and reviewer details. Import into Excel or analysis tools to identify patterns, calculate sentiment, and make data-driven sourcing decisions.
Mercari prices fluctuate. Listings appear and disappear. Without systematic data collection, tracking price movements over time is impossible.
Regular exports create historical records. Build your own price tracking database. Identify optimal buying windows. Spot underpriced inventory before competitors.
Capture product data from any Mercari search, category, or seller shop page.
Data fields included:
Simply perform your search, apply filters as needed, then scroll through results. The extension captures every listing that loads. Export when ready.
Get comprehensive data from specific product pages including information not visible in search results.
Additional data fields:
This mode captures everything displayed on a product detail page. Essential for deep-dive research on specific items.
Build databases of Mercari sellers with comprehensive profile metrics.

Not every export needs every field. The extension includes a field customization panel.
This eliminates post-export cleanup. Your exported files match your workflow immediately.
For automated workflows, enable webhook export. Instead of downloading files, the extension POSTs JSON data directly to your specified URL.
Use cases:
Configure your webhook URL once, then exports flow directly into your systems.
Go to any Mercari page: search results, category pages, product listings, or seller profiles.
Click the Mercari Exporter icon in your Chrome toolbar.
Choose what to extract based on your current page:
Browse normally. Scroll through search results. Visit multiple product pages. The extension captures data automatically as pages load.
Open the extension to see your export list. Preview data. Remove unwanted items. Search within collected data.
Click Export, choose your format, and download your file.
