How do you turn NFT into real money?

I'm curious, could you explain the process of converting an NFT into real money? I've heard about the potential of NFTs as digital assets, but I'm not entirely clear on how one would go about cashing them out. Is it a straightforward process, or does it involve multiple steps and potential risks? Additionally, are there any specific platforms or marketplaces that are commonly used for this purpose? I'd appreciate any insights you can provide on this topic.
