Who does what in the Cardmarket workflow
TCG PowerTools is a listing tool for sellers on Cardmarket. It accepts card lists as CSV files and manages your listings from there. TCG Actana starts one step earlier: the desktop app turns your card images into a batch you can review.

Actana takes your cards in as image files through file selection, drag and drop, or a watched scanner folder. The app suggests the card and printing; uncertain or ambiguous results stay open for review. Condition, finish, and quantity are recorded per copy. The export then turns the reviewed batch into a CSV in the TCG PowerTools import format.
One thing to be clear about: Actana uploads nothing to Cardmarket. Importing the file into TCG PowerTools is your next step, and prices and listings stay under your control there.
What the Actana CSV looks like
The preset is called "TCG PowerTools" in Actana. The slim Magic header with one complete sample row:
cardmarketId,quantity,name,set,condition,language,isSigned,price,finishType,buyPrice,comment
12345,1,Entomb,Odyssey,NM,German,,17.50,Regular,,If you assign storage locations on export, Actana adds a location column after comment. Magic uses this slim schema; the extended schema for Pokémon and the other TCGs adds the variant fields.
That is a German-language Entomb from Odyssey, Near Mint, one non-foil copy listed at 17.50 EUR. Unused fields stay empty.
One file per game
The export creates a separate CSV for each supported game represented in the export. This applies to Magic, Pokémon, and One Piece. The reason sits on the import side: TCG PowerTools always processes a CSV in the context of the game that is active there, and the format has no game column. You do not need an Actana inventory for this export. Actana creates one CSV for each game represented in the reviewed batch.
