Frequently Asked Questions

Is YAML the same as JSON?

YAML and JSON are both data serialization formats, but YAML is a superset of JSON. YAML is more human-readable with its indentation-based structure, while JSON uses brackets and quotes. Every valid JSON document is also valid YAML, but not vice versa.

Will my data be preserved during conversion?

Yes, all data values, nested structures, arrays, and objects are preserved exactly during conversion. The only change is the format syntax used to represent the same data.

Can I convert multi-document YAML files?

Yes, the converter supports multi-document YAML files separated by "---" delimiters. Each document will be converted to a separate JSON object in an array.
