Minecraft xbox 360 cloud to xbox one?

I have recently traded in my 360 for a xb1. I made the critcal mistake of not transfering any of my world's to xb1. So basically all my world's on my hard drive are gone but I did have some 360 world's on the cloud. Any way to retrive these saves without using a 360?

Play it again

No, you have to have both consoles. You need to use Minecraft on the 360 to upload the world to the cloud, before you can download it from the cloud on the Xbox One.
