How to Use JSON to YAML Converter — Clean Output Tool
How to Use the JSON to YAML Converter
Step 1: Paste Your JSON
Paste or type your JSON data into the input field. The tool accepts any valid JSON — objects, arrays, nested structures, or mixed types.
Step 2: Set Indent Size
Choose 2 or 4 spaces for YAML indentation. 2 spaces is the most common convention for Kubernetes and Docker Compose files.
Step 3: Convert
Click Convert to YAML to transform your JSON. Use the example buttons to see how different JSON structures are serialised.
Step 4: Copy or Download
Click Copy YAML to copy the output to your clipboard, or Download .yaml to save a file.
Supported JSON Types
- Objects — become YAML mappings (
key: value) - Arrays — become YAML sequences (lines prefixed with
-) - Strings — quoted automatically when they contain special characters or are ambiguous (e.g. look like booleans or numbers)
- Numbers, booleans, null — rendered as plain YAML scalars
Tips
- String values that look like
true,false,null, or a number are automatically quoted to prevent YAML misinterpretation - The tool works entirely in your browser — safe for config files with secrets
