Can you change crypto to cash?

Hello there, I'm wondering about something related to cryptocurrency. Can you actually change or convert your crypto holdings into cash? I've heard that it's possible, but I'm not entirely sure how the process works or if there are any restrictions or fees involved. Could you please elaborate on this topic and explain the most efficient way to go about it? I'm particularly interested in knowing if there are any trusted and reliable platforms or exchanges that facilitate this type of transaction. Thank you for your time and expertise.
