How can you make bread from pizza dough?
Pizza dough is supposed to be stretchy and pliable, so it is going to be a bit loose. Given those characteristics it's not going to be able to hold a shape that well. You're best off aiming for a ciabatta shape, putting it into a tin or shaping basket. Best of all make a focaccia type bread with it by just spreading it out flat, letting it rise, then dimpling it with your fingers and pouring some olive oil and salt on it before baking.
