What is a TCGPowerTools import file?

Why the import file exists

Cardmarket has tens of thousands of Pokémon products: every set, every printing, every language, plus reverse holo variants, error cards, prerelease stamps, and reprint runs. To list a card on Cardmarket you have to publish it against the exact product ID, otherwise your listing ends up on a different SKU and the buyer sees the wrong card. Doing this manually one card at a time, through the Cardmarket UI, is what keeps most sellers stuck at hobby volume.

TCGPowerTools sidesteps the manual UI by accepting a CSV with all the publishing data in one shot. Once your file is correct, hundreds of cards publish in seconds.

What a row in the file actually contains

• Cardmarket product ID — the numeric identifier of the exact Cardmarket product (set + number + variant + language). This is the single hardest field to populate correctly.
• Price — your asking price in EUR. Most sellers use a price-rule strategy ("trend - 5%", "lowest + 10c", etc.) which TCGPowerTools applies on top of the file.
• Condition — Mint, Near Mint, Excellent, Good, Light Played, Played, Poor.
• Language — EN, DE, FR, IT, ES, JP, etc.
• Quantity — almost always 1 for singles, higher for bulk SKUs.
• Comment — optional public note shown on the listing.

The bottleneck nobody talks about

Building the file row-by-row is what bottlenecks every Cardmarket workflow above hobby volume. Manually finding the correct Cardmarket product ID for one card takes 30-90 seconds. At a few hundred cards that is hours of pure data-entry per session, and the failure mode (wrong product ID = listing on the wrong product page) is hard to spot until a buyer complains.

This is the gap NeoSatoshi was built to close. Photograph cards individually, in table batches, on binder pages, or via a hardware scanner. NeoSatoshi resolves each card to its precise Cardmarket product ID, attaches a current Cardmarket price, and outputs a clean TCGPowerTools-compatible import file. A few tools can create such a file from scans or photos (see our dated comparison); NeoSatoshi does it from single-card photos, multi-card photos, binder pages and scanner batches for Pokémon, One Piece, Disney Lorcana, Yu-Gi-Oh!, Magic: The Gathering, Star Wars: Unlimited and Digimon Card Game. Every column of the file is explained in our TCGPowerTools guide.

How the full pipeline looks

1. Photograph cards (single shot, table batch, best up to about 20, full binder page, or scanner output).
2. NeoSatoshi recognises each card and resolves the Cardmarket product ID + current price.
3. You review the matches and override prices where needed.
4. Download the TCGPowerTools-compatible import file.
5. Load the file into TCGPowerTools and publish to Cardmarket. TCGPowerTools also handles ongoing price-sync.

Common mistakes that break the file

• Picking the base printing of a card when you actually have a stamped or special version (different Cardmarket product ID), or forgetting the reverse holo flag on a reverse holo card (same product, its own flag and its own price).
• Mixing up English and Japanese printings for the same set + number (also a different product).
• Using a stale Cardmarket price from a price guide that has not refreshed in days.
• Listing duplicates with the same product ID instead of incrementing quantity.
