Frequently Asked Questions
What is YAML and how does it differ from JSON? +
YAML (YAML Ain't Markup Language) is a human-readable data serialization format. Unlike JSON, YAML uses indentation instead of braces and brackets, doesn't require quotes around most strings, and supports comments. Both formats can represent the same data structures.
Does this converter handle nested JSON objects? +
Yes, the converter fully supports deeply nested objects, arrays, mixed types, and all JSON data types including strings, numbers, booleans, and null values. Each nesting level is properly indented in the YAML output.
Is my JSON data sent to a server? +
No. The conversion happens entirely in your browser using JavaScript. Your data never leaves your device, making it completely safe for sensitive or private JSON data.
What happens if my JSON is invalid? +
The converter will display a clear error message indicating that your JSON is invalid and show the specific parsing error. Fix the syntax issue in your JSON and the conversion will work automatically.
Can I convert YAML back to JSON? +
This tool converts JSON to YAML. For the reverse conversion, check out our YAML to JSON converter tool which handles the opposite direction.
