Can i play gta online with my existing save file from story mode?
Quick Answer
No, there is no evidence that existing Grand Theft Auto V story mode save files can be used in Grand Theft Auto Online, as the two are separate game modes with distinct progression systems.
Explanation
Grand Theft Auto Online is a standalone online multiplayer component of Grand Theft Auto V, released separately across different platforms. While it exists within the same fictional world of San Andreas and Los Santos, it operates as an independent game with its own progression, character customization, and multiplayer mechanics. The provided evidence does not mention any compatibility between story mode save files and Online mode. Typically, single-player and online modes in games like this are designed separately, with Online mode requiring a new character creation process. Therefore, existing story mode progress is unlikely to transfer over to GTA Online.
