Good day!
The issue is that the CSV file imported into Deckbox needs to have a header row, which tells Deckbox what each column contains. The TCGPlayer CSV has
no header row, and just starts with the first card. You need to open the file in Excel (or a similar spreadsheet program) to edit it.
I've converted the CSV you attached and have done a test import to make sure it went smoothly. However, here's some notes in case you have others like this one:
- The first column is how many of that specific printing of the card you have, and needs to be labeled "Count".
- The next two columns both have card names in them. I'm not sure why there's two. My bet is that one of the columns (probably the first) is for the English name, while the other would be for the localized card name. All yours are English, so can't be sure. You would need to delete one of the columns, and label the other one with "Name".
- Fourth column needs to be labeled "Edition" (you don't necessarily have to have this column, but if you didn't include it, all of them would be imported with no edition set).
- Fifth column appears to be "Card Number". NOTE: TCGPlayer uses different card numbers for older sets. This won't affect import, except in the case of alternate versions of the card within the same set. See final note below.
- Sixth column is the 3-letter code for the edition and isn't used by Deckbox. Deleted.
- Not sure on the seventh column, but I'm betting this is for indicating foil / nonfoil. Your list doesn't appear to include foil cards. If you have any foil cards, you would need to label this column "Foil", then delete "Normal" from all the non-foils, and make sure just "foil" is in the column for foils (TCGPlayer might use the official term "premium"; change it to "foil").
- Eighth and ninth columns are "Condition" and "Language", respectively. Like with "Edition", you don't have to have these columns, but if you don't, then your cards will lack a condition or language icon (but I think the pricing will be based on Near Mint, and the language defaults to English).
- Deleted the rest of the columns. Not sure what those numbers in the final two columns are.
You'll also have to be careful with alternate arts within the same sense, like with your Alliances cards. TCGPlayer adds an extra descriptor to the card name (like "red armor") which will throw an error if it isn't removed. But that means you'll have to check to Deckbox versions of the card to make sure the correct one is selected. IMPORTANTLY, Deckbox uses different card numbers than does TCGPlayer (like TCG had Lim-Dul's High Guard as 55a and 55b, but Deckbox uses 17 and 18; your Stench of Decay is 61b on TCG, but 28 on Deckbox). If you don't carefully correct these cards, Deckbox will display the wrong art, and will also incorrectly group the cards.
