Bulk Import
Upload a CSV or XLSX file, map incoming columns, and merge cards into your collection.
Drag and drop your file here or choose a file manually.
Getting started with bulk upload
Use a CSV or XLSX file with one row per card. The importer requires a card identifier and a quantity, and it also uses player, set, and year when they are present to match the right card more accurately.
Required
- Card # / Card Number / Card No / Number
- Qty / Quantity / Count / Owned
Optional but helpful
- Player / Player Name / Name
- Set / Set Name / Product
- Year / Season
Keep values clean and consistent. Blank quantity is treated as 1, negative quantities are rejected, and matching gets better when the set and year are included. Sets can be named with or without the manufacturer and series, such as MVP, Upper Deck MVP or Upper Deck Series 1.
