Frequently Asked Questions

How do I convert JSON to YAML?

Paste your JSON data into the input field and click "Convert to YAML". The tool instantly converts your JSON to properly formatted YAML. You can then copy the result or download it as a .yaml file.

What is the difference between JSON and YAML?

JSON uses braces and brackets with strict syntax, while YAML uses indentation-based formatting that is more human-readable. YAML supports comments, multi-line strings, and anchors. YAML is commonly used for configuration files (Docker, Kubernetes, CI/CD), while JSON is preferred for APIs and data exchange.

Does this tool handle nested JSON objects?

Yes, the converter handles deeply nested JSON objects, arrays, mixed types, and complex data structures. All nesting is preserved accurately in the YAML output with proper indentation.

Can I customize the YAML indentation?

Yes, you can choose between 2-space and 4-space indentation for the YAML output. The default is 2 spaces, which is the most common convention for YAML files.

Is my data secure when using this converter?

Absolutely. All conversion happens locally in your browser using JavaScript. Your data is never uploaded to any server. This means even sensitive configuration data can be safely converted without privacy concerns.
