What does the YAML to JSON do?
YAML supports indentation-based maps, sequences, scalars, and features that do not have identical JSON syntax. The converter resolves the YAML document and serializes the resulting data model as JSON.
Common uses
- Convert deployment configuration for an API
- Inspect YAML as explicit JSON structures
- Move data between configuration formats
