JSON to YAML Converter
Convert JSON into readable YAML for configuration files, CI pipelines, and developer tooling. Objects become mappings, arrays become sequences, and primitive JSON values retain their meaning.
Convert JSON to YAML
Paste JSON or upload a .json file to create clean, two-space-indented YAML entirely in your browser.

CSV is best for arrays of records; XML attributes use @_ keys in other formats.
How JSON maps to YAML
The converter applies clear rules so you can understand the output before using it in another tool or workflow.
Objects become mappings
JSON object keys and nested structures are written as YAML mappings without sorting the keys.
Arrays become sequences
JSON arrays are represented as YAML sequences, including arrays of objects and nested arrays.
JSON types are preserved
Strings, numbers, booleans, and null values are emitted using their corresponding YAML scalar types.
