How do I transfer my Bitcoin to my bank account?

Could you please elaborate on the process of transferring Bitcoin to a bank account? I'm interested in understanding the steps involved, including any necessary conversions or platforms I might need to use. Is it a complex process, or is it relatively straightforward? Also, are there any fees or charges associated with this type of transaction? And how long does it typically take for the funds to reflect in my bank account? Your detailed explanation would be greatly appreciated.
