2D level editor saving

Hello everyone

I will make a simple 2D drag and drop level editor. But one thing is bugging me, is that suppose i have completed making a level and trying to save it how will i achieve that. How would i "save" my level and load it in another scene? Should i create a text file for the level with positions of all the objects (is this even possible?)

Note: i want this to be done after i have built my project

Thanks in adv.
