Convert valid JSON into YAML, XML, or CSV without sending the source to a remote service. Preview the generated text, copy it, or download it in the selected format.
Conversion is a representation change, and not every target format maps perfectly to every JSON structure. Review the output against the requirements of the system that will consume it.
YAML can express mappings, sequences, and scalar values in a human-oriented syntax. The converter emits a straightforward representation and quotes values when needed to avoid confusing strings with booleans, numbers, nulls, or YAML punctuation.
YAML supports features that JSON does not, including comments, anchors, and multiple documents. A JSON-to-YAML conversion cannot create those authoring features because they are absent from the source data.
XML represents a tree of named elements and attributes, while JSON distinguishes objects and arrays directly. Conversion therefore needs wrapper and item element names. Consumers with a strict XML schema may require different naming, namespaces, attributes, or ordering than a generic conversion provides.
CSV is tabular, so it works best for an object or an array of similarly shaped objects. Nested objects and arrays do not have one universal CSV mapping and may be serialized inside a cell. For analytics or database imports, decide explicitly whether nested values should be flattened, joined, or split into related tables.
A flat object or an array of flat objects with similar keys.
Not necessarily. Schema-specific element names, namespaces, attributes, and order may need a custom transformation.
No. JSON has no comments, so there is no comment data to carry into the YAML output.
