Convert JSON, XML, CSV and YAML

How the conversion works

• XML attributes become keys that start with @, and element text next to attributes becomes #text. The same keys turn back into attributes when you convert to XML.
• To XML: an object with one key uses that key as the root element. Anything else is wrapped in <root>, and array items become <item>.
• To CSV: each array item becomes a row. Nested fields are flattened to dot paths such as customer.name. If the data is wrapped in a single key, such as {"orders": [...]}, the array inside is used.
• From CSV: the first row is the header. Numbers and true/false are typed, and dot paths in the header are turned back into nested objects.
