About JSON to YAML
Convert JSON data to YAML format. YAML is more human-readable and commonly used for configuration files in DevOps tools like Docker Compose, Kubernetes, and Ansible. JSON comments are not supported, so the output will be clean YAML without comments.

What is JSON to YAML Conversion?
JSON to YAML conversion transforms JSON (JavaScript Object Notation) data into YAML (YAML Ain't Markup Language) format. This is useful when you need more human-readable configuration files or want to use DevOps tools that prefer YAML.
JSON is widely supported by programming languages and APIs, but YAML offers better readability with its indentation-based structure. YAML is commonly used in Docker Compose, Kubernetes, Ansible, and many CI/CD pipelines.
This free tool converts JSON to YAML while preserving the data structure, including nested objects, arrays, and primitive values. All processing happens in your browser for privacy.
Features
Data Type Preservation
Correctly converts strings, numbers, booleans, and null values from JSON to YAML.
Nested Structure Support
Handles deeply nested objects and maintains the hierarchical structure.
Array Conversion
Converts JSON arrays to proper YAML lists using hyphen notation.
Customizable Output
Choose between 2 spaces or 4 spaces for indentation to match your style.
Download & Copy
Download the converted YAML as a file or copy it directly to your clipboard.
Error Handling
Provides clear error messages when JSON syntax is invalid.
JSON to YAML Conversion Guide
Objects: JSON {"key": "value"} becomes YAML "key: value".
Nested Objects: JSON nested braces become YAML indented key-value pairs.
Arrays: JSON arrays [1, 2, 3] become YAML lists with hyphens.
Strings: JSON quoted strings become YAML strings (quotes optional for simple strings).
Numbers: JSON numbers remain as numeric values in YAML.
Booleans: JSON true/false become YAML true/false.
Null: JSON null becomes YAML null.
Frequently Asked Questions
Why convert JSON to YAML?
YAML is more human-readable than JSON due to its indentation-based structure. Many DevOps tools like Docker Compose, Kubernetes, and Ansible prefer YAML for configuration files.
Can I add comments to the YAML output?
JSON does not support comments, so the converter cannot automatically add them. However, you can manually add comments (lines starting with #) to the YAML output after conversion.
What JSON features are supported?
This tool supports all standard JSON features including objects, arrays, strings, numbers, booleans, and null values. Nested structures of any depth are handled correctly.
Is my data secure?
Yes. All processing happens entirely in your browser using JavaScript. Your JSON data never leaves your device and is not sent to any server.
