Cardmarket Stock Exporter

Thank you to more than 1,000 users who have installed Cardmarket Stock Exporter! Many of the improvements in recent versions came straight from your reports. The extension exports your Cardmarket stock and your want lists to CSV. You make changes to prices, comments and wants in a spreadsheet and send them back through the CSV. Everything runs in your browser, in the Cardmarket tab you are already logged in to. It is free, shows no ads and needs no account of its own. STOCK EXPORT • Your complete stock, or only the sets you select • All 20 trading card games Cardmarket supports and all 17 card languages • The stock is read set by set, and large sets are split further • Completeness check: after the export, each set is compared with Cardmarket's own card counts. If something is missing, the log names the set. • Optional price trend and 1-, 7- and 30-day averages, separate for each print variant, plus a column showing how far your price is from the trend • Set code and collector number as separate columns (for some games the collector number needs the trend option) • Semicolon-separated UTF-8 CSV for Excel and Google Sheets BULK UPDATE OF PRICES AND COMMENTS • Change prices in the spreadsheet, upload the CSV, check the preview, confirm • The preview shows the old and the new price before anything is saved • Dry run is on by default: the run only tests and saves nothing • A limit on the price change in percent catches typos • Only rows you changed are touched. Language, condition and quantity of a listing stay as they are. • Comments can be updated in the same run if you want • Reads CSVs with semicolons or commas, and prices with a decimal comma or a decimal point • Optional Fast Mode for large runs. If a row fails, it automatically takes the standard route. WANT LISTS • All want lists of a game in one CSV, with quantity, languages, minimum condition and maximum buy price • Attributes such as foil or signed appear in the CSV as they do on Cardmarket: Y for must be, N for must not be, Any for no preference • Edit wants through the CSV: only the fields you changed are written. Everything else stays as it is on Cardmarket. • Every change is read back from Cardmarket after saving and only then counts as done. A deletion (delete=Y) counts once the entry is gone. • Dry run is on by default here as well • If Cardmarket throttles the requests, the run stops and reports how many entries were left untouched • Values a spreadsheet has altered (a price turned into a date, for example) are skipped and listed in the log USING IT • Interface in German and English • The popup can be pinned as its own window, so it stays open during long runs • Every run shows its progress and can be aborted PRIVACY • No tracking and no analytics. The extension talks only to cardmarket.com. • Your username and password are never read. The CSV is created in your browser. • Stored locally: only your language choice and a cache for price trends (12 hours) • The source code is public on GitHub under GPL-3.0 PERMISSIONS • activeTab, tabs, scripting: find the open Cardmarket tab and work in it • downloads: save the CSV • storage: language choice and trend cache • Site access: www.cardmarket.com only HELP, SOURCE CODE, CHANGELOG https://github.com/LUPZN/cardmarket-stock-exporter https://github.com/LUPZN/cardmarket-stock-exporter/blob/main/CHANGELOG.md Unofficial tool.
