Frequently Asked Questions

Why convert from YAML to JSON?

While YAML is great for human-readable configurations, JSON is widely used in APIs and web services. Converting to JSON makes your data compatible with various systems and programming languages that expect JSON format.

What's the difference between compact and formatted JSON?

Compact JSON removes all whitespace and newlines, making the output smaller but harder to read. Formatted JSON includes indentation and line breaks, making it more readable for humans but larger in size.

Are all YAML features supported?

Our converter handles most common YAML features including nested objects, arrays, and basic data types. Some advanced YAML features like anchors and aliases might need manual adjustment after conversion.

Is the conversion secure?

Yes, all conversion happens in your browser - no data is sent to any server. For added security, you can enable HTML escaping to prevent potential XSS vulnerabilities when using the JSON in web applications.
