How to transfer USDC to USD?

Can you explain the process of converting USDC to USD in a clear and concise manner? I'm interested in understanding the steps involved and what platforms or exchanges I can use to facilitate this conversion. Additionally, are there any fees or charges associated with this process, and if so, how do they vary across different platforms? Is it necessary to have a specific type of wallet or account in order to complete this transaction? Lastly, how long does the conversion process typically take, and are there any potential delays or issues that I should be aware of?
