What does the JSON to YAML do?
Objects become YAML mappings and arrays become sequences. The conversion preserves data values but cannot restore comments or formatting that were not present in the JSON data model.
Common uses
- Create a YAML configuration from an API payload
- Translate JSON examples for deployment files
- Make nested configuration easier to edit
