How is the level publishing system implemented in the Geometry Dash game?

Question

Unity

Hello! While playing geometry dash, I wondered how the creator of this game made the system for creating levels, namely saving objects on it and publishing the level to the network. I would like to know how it can be repeated, what needs to be studied. I assume that the save system works like that with Json , maybe it saves the position of the object and other functions, and transfers them to a Json file, after which all data (level) is loaded to the server. Any suggestions on how it's implemented? If something is not clear, write, I will correct the question.

It is possible and so in principle. You can push a custom binary format
