CSV Converter

Manabox → TCGPlayer

Convert a Manabox collection export + your TCGPlayer catalog into a staged-import CSV ready to upload directly to TCGPlayer Seller Portal. Runs entirely in your browser — no data leaves your machine.

Why two files?

TCGPlayer matches inventory by internal SKU IDs that only exist in their catalog export. This tool joins your Manabox quantities and conditions onto the official SKU rows, so the import goes in clean.

① Manabox CSV
Drop CSV here Manabox iOS export · Name, Set code, Foil, Condition, Quantity…
② TCGPlayer Catalog
Drop CSV here Pricing tab → Export Filtered CSV (covers your relevant sets)

Upload both CSV files to continue.

How to get the two CSV files

1 Manabox export

  1. Open Manabox on your phone or tablet.
  2. Go to your Collection.
  3. Tap the share / export icon (top right).
  4. Choose Export as CSV.
  5. Save the file and upload it to the tool above.
The export includes card name, set code, collector number, condition, foil status, and quantity — everything the converter needs.

2 TCGPlayer catalog export

  1. Log into TCGPlayer Seller Portal.
  2. Go to Pricing (or Price Management).
  3. Filter by the sets your Manabox cards belong to.
  4. Click Export Filtered CSV.
  5. Upload that file to the tool above.
The catalog CSV contains TCGPlayer's internal SKU IDs. The converter uses these to build the import file — that's why both files are required.
