Can I transfer money from a Starbucks gift card to a debit/credit card?

I have an unused amount of about $30 on a Starbucks gift card, and I'd really like to transfer those funds back to my debit card. I saw an option to transfer the money to a different card, but this only seems to work with transferring the funds to a different Starbucks gift card. Is it possible to put the money back onto a debit or credit card?
