How do you transfer a grand theft auto v story mode character to gta online?

GTA Online operates on a separate character system from GTA V's Story Mode. Story Mode features fixed protagonists like Michael, Franklin, and Trevor, while GTA Online allows players to create and customize their own unique avatar. There is no built-in transfer mechanism between these two distinct character frameworks. Any attempt to move a Story Mode character into GTA Online would require unofficial modifications or cheats, which are not supported by Rockstar Games and may violate terms of service.
