About JSON ↔ YAML / XML Converter

Bi-directional conversions between JSON, YAML, and XML with fine-grained mapping controls

Multi-Format Engine100% Client-Side
Data Flow:Input: JSON / YAML / XML➔Output: JSON / YAML / XML
A JSON, YAML, and XML converter transforms structured data between JSON, YAML, and XML formats while preserving the underlying data hierarchy, values, and types whenever possible.

This multi-format converter parses JSON, YAML, and XML documents into a normalized in-memory data representation and serializes it into the target format. It provides fine-grained control over XML root elements, array containers, XML attribute prefixes (@), text content (#text), null value representations, and YAML indentation/quoting.

Bi-directional conversion: JSON ↔ YAML, JSON ↔ XML, YAML ↔ XML
Configurable XML root tags, attribute prefixes (@), and array item wrappers
YAML indentation (2/4 spaces) and document headers (---)
Instant format swapping with automatic input-output handoff
Important Note: JSON and YAML map symmetrically to objects and arrays. XML conversion is mapping-dependent because XML uses elements, attributes, text nodes, and namespaces that have no single universal representation in JSON or YAML.
Strict client-side execution. Your payload is never transmitted across the network or stored in external servers.
