Convert YAML to JSON, or JSON to YAML — supports nested objects and arrays, both directions.
Yes, nested objects and arrays of any depth are supported in both conversion directions.
Standard key-value pairs, nested mappings, lists, strings, numbers, booleans, and null values are supported. Advanced YAML features like anchors, aliases, and multi-document files are not.
YAML is generally considered more human-readable for configuration files since it doesn't require quotes around keys or curly braces, though JSON remains the standard for data exchange between programs.
This tool converts YAML documents to JSON, or JSON to YAML, handling nested objects and arrays. It's useful for developers working with configuration files, Kubernetes manifests, CI/CD pipelines, and APIs that use either format.
Both YAML and JSON represent the same underlying data structures — objects (key-value mappings) and arrays (ordered lists) — but with different syntax. JSON uses curly braces, square brackets, and quoted keys, making it precise and easy for programs to parse. YAML uses indentation and minimal punctuation instead, which many developers find easier to read and write by hand, especially for configuration files, at the cost of being more sensitive to exact indentation.
Converting between YAML and JSON is useful when an API expects one format but your source data is in the other, when debugging by viewing YAML config in more explicit JSON form, or when migrating a project's configuration format. Since both represent identical underlying data, conversion between them is lossless for standard data types.
All conversion happens directly in your browser — your data is never sent to a server.
