GTA 5 cheat codes do not work in GTA Online as they have been disabled by Rockstar to prevent players from causing mayhem for one another. Pretty obvious really. This also means, no there is no GTA Online money cheat, although on occasion players have discovered some rather inventive workarounds in the past.
It's worth noting that any GTA 5 Cheat Codes that work in single-player have been disabled in GTA 5 Online, with this applying to both the open world and Job segments of the game.
