Turns a piece of structured data, such as an object or a list, into a single YAML text string. Use this when a system or file you produce expects YAML, a plain-text format that lays out fields one per line. There is nothing to configure: hand it your data and it returns the YAML text.

​
Sample data

This example formats one object into YAML. Each field becomes its own line, and the price keeps its number form. Input: 
{
    "product": {
        "sku": "SCARF-01",
        "name": "Wool scarf",
        "price": 24.95
    }
}
Output: 
{
    "product": "sku: SCARF-01\nname: 'Wool scarf'\nprice: 24.95\n"
}
