How do I cash out crypto to real money?

Could you please explain to me the process of converting my cryptocurrency holdings into actual cash? I've been hearing a lot about crypto and I'm considering selling some of my tokens. However, I'm a bit confused about the entire cashout process. Do I need to use a specific exchange or can I do it through any platform? Are there any fees or commissions involved? And how long does it usually take for the funds to reach my bank account? I would really appreciate it if you could provide me with a step-by-step guide on how to cash out crypto successfully.
