Cardmarket Stock Exporter

Exportiert Cardmarket-Lagerbestand als CSV + Bulk-Price-Update via CSV-Import. by LUPZN

Export your complete Cardmarket inventory to CSV — the easy way. Built by LUPZN, the indie developer behind a growing line of privacy-first browser tools. Cardmarket does not offer a built-in way to export your full seller stock. Their web UI limits unsorted stock views to 300 entries and has no bulk CSV export button. If you manage thousands of cards, keeping an accurate inventory (quantity, unit price, total value) is painful. This LUPZN extension scrapes your own stock listings page-by-page, per expansion, and builds a clean CSV with everything you need for accounting, insurance, or portfolio tracking. Tested on collections with 19,000+ cards. Works reliably. ━━━━━━━━━━━━━━━━━━━━━━ ✨ FEATURES 📊 Full stock export — handles 20,000+ cards without issues 🎮 8 TCG games — Pokémon, Magic, YuGiOh, Lorcana, One Piece, Flesh and Blood, Dragon Ball Super, Digimon 🌍 5 languages — German, English, French, Spanish, Italian 📈 Live progress bar with current expansion, page number, running total ⏹️ Cancel button — abort mid-export and keep what was collected 📌 Pin-to-window — detach the popup so it doesn't close when you click elsewhere 💰 Auto-calculates total value per row and grand total 🔄 Deduplication via article ID — no duplicate rows ⚡ Rate-limit aware — auto-pause on HTTP 429 📁 Excel-ready CSV — UTF-8 BOM, semicolon separator 🔁 Bulk price update via CSV import (v2.0) ━━━━━━━━━━━━━━━━━━━━━━ 📋 CSV COLUMNS ArticleID, Name, ExpansionCode, Expansion, Rarity, Language, Condition, ConditionFull, Comments, Price_EUR, Amount, Total_EUR, ProductUrl ━━━━━━━━━━━━━━━━━━━━━━ 🚀 HOW TO USE 1.

A: Unsorted views are capped. The LUPZN extension forces sorted requests and iterates each expansion individually to bypass the cap. Q: Will this get my account banned? A: The extension uses reasonable request pacing (default 500ms between pages) and respects rate limits. Standard GET requests. Use at your own risk — the author accepts no liability. Q: Can I export a single expansion only? A: Yes — set Max Pages to a low number, or open a URL filtered to a specific expansion before starting. Q: CSV opens wrong in Excel? A: Use Data → From Text/CSV, set delimiter to semicolon (;) and encoding to UTF-8. Q: How does the bulk price update work? A: Edit the Price_EUR column in the exported CSV, save it, and re-import via the extension. LUPZN handles the per-article API call with proper rate limiting. ━━━━━━━━━━━━━━━━━━━━━━ 🐛 SUPPORT & SOURCE Source code, issues, and feature requests: https://github.com/lupzn/cardmarket-stock-exporter More LUPZN extensions: https://github.com/lupzn ━━━━━━━━━━━━━━━━━━━━━━ ❤️ LIKE THIS LUPZN TOOL?
