No context was given, but if you’re talking about YAML is a serialized data format that we can say is a competitor of JSON. It is simpler and more economical.

You can use it whenever you think it fits your every need. It’s usually a good substitute for JSON. But I wouldn’t use it on external things because a lot of people won’t know or won’t be able to access this format. JSON and XML became universal standards, YAML did not. But generally I like it better. You don’t have a specific criterion to adopt you on internal things that won’t need to communicate with anything you don’t have control of.

The fact that fewer people use makes it harder to find information and help, but it’s also mouse to need.

Although simpler it is offers more than JSON. A little less than XML which is extremely complex.
