You can import your lists from IGDb. Each list has to be imported separately. All items in the list will be added to the collection you choose.

1. Login to your account and go to your profile. The default activity lists can be exported from here. Click on the list you want to export and download it as CSV.
2. For your custom lists, please visit the "My Lists" page.
3. Upload the CSV file and choose the collection you want to import into.
