You can upload files and import a collection in bulk. This is useful if you have already catalogued your collection and don't want to scan/manually add your cards again.
To import a collection, head to the Import/Export section of the Build page and select Import.
You are able to upload either a .CSV or .TXT file in a variety of formats. If you can't see a format that matches your file, check this article for instructions on editing your file to match our Simple CSV format.
Once you have uploaded your file, wait for an email with the results of the import. This may take a few minutes depending on the size of the collection you are importing. Once you receive this, your cards will be in the Staging Area (in the Add Cards section of the Build page).
If there are any errors, you will receive an email with a file containing the cards that failed to import (the others will have been added). This may be due to your file having a different naming convention for cards or sets - for example, we require Magic 2015 for cards from that set but other platforms may use Core Set 2015. Get in touch if this is happening and we can help you match our naming convention.
Use the Staging Area to review your cards before committing them to your collection.
