YAML Validator
Validate YAML syntax and view parsed result as JSON
This validator parses YAML and displays the result as JSON. It supports basic YAML features including nested objects, arrays, strings, numbers, booleans, and null values.
1. What is YAML?
YAML (YAML Ain't Markup Language) is a human-readable data serialization format. It uses indentation to represent structure and is commonly used for configuration files in tools like Docker, Kubernetes, and CI/CD pipelines.
2. How does it work?
Paste your YAML content in the input field and click Validate. The tool will check the syntax and display the parsed result as JSON. If there are errors, you'll see detailed error messages with line numbers.
Common YAML Syntax
- Key-value pairs: key: value
- Nested objects: use indentation (2 spaces)
- Arrays: use dash (-) prefix
- Comments: start with # character
- Strings: can be quoted or unquoted
- Booleans: true, false
- Null: null or ~
