YAML (YAML Ain't Markup Language) is a human-friendly format for configuration files in Docker, Kubernetes, and GitHub Actions. JSON is dominant for APIs and JavaScript. Converts YAML to JSON with proper type detection for strings, numbers, booleans, null, and nested structures.
Paste your YAML content into the input field and the JSON equivalent appears instantly on the right. The tool handles standard YAML features including nested mappings, sequences (arrays), multi-line strings, anchors, aliases, and all standard scalar types. Invalid YAML shows a clear error message indicating the line and nature of the syntax error.
YAML-to-JSON conversion is common when working with Docker Compose files, Kubernetes manifests, GitHub Actions workflows, Ansible playbooks, and other DevOps tools that use YAML configuration. Developers convert YAML to JSON for programmatic processing, API testing with tools like Postman, validation against JSON Schema, and integrating configuration data into JavaScript applications.
The tool uses the js-yaml library to parse YAML 1.2 documents. It supports all YAML data types: strings, integers, floats, booleans, null, timestamps, and binary data. Complex features like anchors (&anchor) and aliases (*anchor) are resolved during parsing. Converts single YAML documents to JSON with 2-space indentation for readability.
Paste your YAML content into the input field. The tool parses the YAML structure and outputs the equivalent JSON with proper formatting and indentation.
The tool supports YAML 1.2 features including nested objects, arrays, multi-line strings (literal and folded), anchors, aliases, and all standard data types.
The tool processes the first YAML document only. If you have multiple documents separated by ---, split them into separate conversions.
