Frequently Asked Questions

What's the difference between JSON and YAML?

JSON (JavaScript Object Notation) is more compact and widely used for APIs, while YAML (YAML Ain't Markup Language) is more human-readable and commonly used for configuration files. YAML supports comments and multi-line strings, making it ideal for config files.

Is my data secure when using this converter?

Yes, absolutely. All conversion happens entirely in your browser using JavaScript. Your data never leaves your device or gets sent to any server, ensuring complete privacy and security.

Can I convert YAML comments to JSON?

JSON doesn't support comments, so YAML comments will be stripped during conversion. However, when converting from JSON to YAML, you can manually add comments to the resulting YAML file.

What file formats are supported?

You can upload .json, .yaml, .yml, and .txt files. The tool automatically detects the format based on content structure and syntax.

How do I handle multi-document YAML files?

This converter works best with single-document YAML files. For multi-document YAML (separated by ---), consider splitting them into separate conversions for better results.
