Which indentation level should I choose?

Choose 2 spaces for compact YAML (common in web configs) or 4 spaces for more readable indentation (common in some application configs). Both are valid YAML.

How does the converter handle nested objects and arrays?

Nested objects become indented YAML maps, and arrays become YAML list items (lines starting with -). Deep nesting is preserved as-is from the JSON structure.

Can I use this tool on mobile devices?

Yes, this tool works on any device with a modern browser including phones and tablets.

Does this tool support syntax highlighting?

Yes, the tool provides color-coded syntax highlighting to make your code easier to read and debug. Different elements like strings, numbers, and keywords are shown in distinct colors.

Frequently Asked Questions

Is my data secure?

Yes, conversion happens entirely in your browser. No data is sent to any server.

You can choose 2 or 4 spaces for indentation. The default is 2 spaces.

Can I copy the output directly?

Yes, click the 'Copy' button below the output textarea to copy the YAML to your clipboard.

How It Works

Paste JSON: Enter any valid JSON — from flat key-value pairs to deeply nested objects and arrays.
Convert instantly: The tool transforms JSON to YAML with proper indentation, removing quotes from string keys and translating null, boolean, and numeric types.
Configure output: Set indentation width (2 or 4 spaces) and choose whether to use block or flow style for collections.
Copy the YAML: The result is ready to paste into config files, CI/CD pipelines, or Kubernetes manifests.

Why Convert JSON to YAML?

YAML is the preferred configuration format for infrastructure tools like Kubernetes, Docker Compose, GitHub Actions, Ansible, and Helm charts — it's more human-readable than JSON, supports comments, and doesn't require every string to be quoted. Converting API responses, package.json sections, or data structures from JSON to YAML is a frequent task in DevOps and backend development workflows. YAML's indentation-based structure is easier to read for humans, while JSON is preferred for APIs and programmatic generation — this converter bridges the two.

Type Mapping

Strings → unquoted if safe, quoted if containing special characters
Numbers → numeric YAML scalars preserved as-is
Booleans → true / false in YAML
null → null or ~ in YAML
Arrays → YAML block sequences with - prefix
Objects → YAML mappings with key: value pairs
