Microsoft Points were discontinued in 2013 in favour of local currencies. Therefore you can only purchase digital content using your own currency on the Xbox One.
If you still have remaining Microsoft Points, yes, however Microsoft has transferred from Points to actual Dollar value."As part of the next Xbox 360 system update, Microsoft Points will be retired, and transactions on Xbox will take place using your local currency instead of Microsoft Points. Microsoft Points Cards you purchase from retailers will continue to be redeemable on your console and Xbox.com until further notice. Microsoft has no plans to discontinue acceptance of previously purchased Points cards and codes. For more information, see Microsoft transition to local currency." - Microsoft Xbox
