Poke Genie export
Oak currently supports Poke Genie CSV exports directly. Export your own collection from Poke Genie, then use the normal importer.
Bring your Pokémon into Oak Coliseum with a Poke Genie export or a simple spreadsheet you maintain yourself.
Oak Collection Template
Download the template, replace the example rows with Pokémon you own, then save it as a CSV file.
Step 1
One Pokémon per row. These four columns are all Oak needs for a usable team recommendation.
Step 2
These optional columns help preserve more of your collection record, but are not required to import.
Step 3
Log in, open Inventory, choose Import CSV, and review every row before anything is added. You may add to your current collection or deliberately replace it using the protected replacement option.
