This extension allows you to use a CSV file to fill the "List bulk items" option in Cardmarket.
Download it on the Chrome Webstore or Firefox's addons.
No! It's not a tool designed to import a CSV of your collection all at once. This extension's primary focus is to fill the "List bulk items" form in Cardmarket; this means that we're also limited by the usefulness of this form - Cardmarket can only show (and take) up to 100 items at a time, so we would have to import the items in batches of 100 different articles; the extension tries to make this process as seamless as possible, but it can't do more than that.
My recommendation is to split your CSVs by expansion, and then importing each rarity one by one.
Yes! Partially! Currently Magic is the one that supports more properties, but all games support basic importation. More fields planned in the future (PRs welcome!).
Yes! If you have, for example, foil and non foil rows on your CSV, the extension will add them separately.
It can happen! I can't guarantee there are no bugs or issues in some older set tables / names, so it's possible it fails to fill the table correctly. Always double check the filled form before submitting the cards for sale! I take no responsibility for mistakenly made listings.
Yes! Although they have not checked / vetted the extension, I have confirmed with support that it was okay for me to publish it and it's okay for users to use.
No! Even though the extension is allowed to read and write specifically on websites where the url matches *://*.cardmarket.com/*/*/Stock/ListingMethods/BulkListing*, the extension does not read or write over your personal information. It simply reads and fills the table of bulk listing in order to do it's job!
The entire code is open source and you can verify it here; you can even clone this repository and launch it yourself locally if you don't trust the store version.
I have improvements planned when I find the time to work on them! Check the TODO file for the planned upgrades.
I will accept contributions to this project. Open a pull request to the develop branch and I'll review it as soon as I can!
