YAML to JSON Converter
Convert between YAML and JSON formats instantly with our free online YAML converter. Transform YAML configuration files to JSON and vice versa with perfect formatting. Essential for developers, DevOps engineers, and anyone working with data serialization formats.
Frequently Asked Questions
YAML (YAML Ain't Markup Language) is a human-readable data serialization format commonly used for configuration files, data exchange, and infrastructure as code. It's popular in Docker, Kubernetes, Ansible, and CI/CD pipelines due to its clean, readable syntax that uses indentation instead of brackets.
YAML is more human-readable with minimal syntax, using indentation and colons. JSON is more structured with brackets and braces, making it better for programmatic parsing. YAML supports comments and is often preferred for config files, while JSON is standard for APIs and web data exchange.
Paste your YAML content into our converter and select 'YAML to JSON'. The tool parses the YAML structure (keys, values, lists, nested objects) and outputs properly formatted JSON with brackets, quotes, and commas. Perfect for API integration and JavaScript applications.
Yes, simply paste your JSON into the converter and select 'JSON to YAML'. The tool transforms JSON's bracket-heavy syntax into clean, indented YAML format. This is useful for creating readable configuration files from API responses or JSON data.
Yes, our YAML converter handles complex nested objects, arrays, and mixed data structures. It properly maintains hierarchy when converting between formats, ensuring your data relationships are preserved whether you're converting YAML to JSON or JSON to YAML.
YAML is widely used for Docker Compose files, Kubernetes manifests, GitHub Actions workflows, Ansible playbooks, Travis CI configs, Swagger/OpenAPI specifications, and application configuration files. Its readable format makes it ideal for version control and team collaboration.
While possible, JSON is the standard for REST APIs due to better browser support and parsing speed. However, YAML is commonly used for API documentation (OpenAPI/Swagger specs) and can be converted to JSON for actual API communication using our converter.
YAML is indent-sensitive and requires consistent spacing (usually 2 or 4 spaces, never tabs). Our converter provides error messages for invalid YAML. Common issues include mixed tabs/spaces, inconsistent indentation levels, and missing colons after keys.
Yes, YAML is case-sensitive for keys, values, and boolean literals. 'Name' and 'name' are different keys. Boolean values like 'true', 'false', 'yes', 'no' must be lowercase or properly quoted if you want them as strings.
When converting YAML to JSON, comments are stripped because JSON doesn't support comments. The data structure is preserved, but explanatory comments in your YAML will not appear in the JSON output. Keep original YAML files for documentation purposes.
YAML supports multi-line strings using '|' (literal, preserves line breaks) or '>' (folded, converts to single line). When converting to JSON, these become standard JSON strings with appropriate escape characters like \n for line breaks.
YAML is generally preferred for configuration files due to readability, comment support, and minimal syntax. JSON works better for programmatic configs and when strict parsing is needed. Many tools support both formats - use our converter to switch between them as needed.
