json2yaml: JSON to YAML Converter

This package, `json2yaml`, provides a command-line utility and a programmatic API for converting JSON data into human-readable YAML format. First released with a Node.js `0.2.0` engine requirement, its current stable version is 1.1.0. The tool primarily aims to pretty-print JSON, transforming it into the more visually appealing, whitespace-based YAML notation, leveraging the fact that JSON is technically a proper subset of YAML. This means any valid JSON is also valid YAML, but `json2yaml` focuses on converting to the more common, indented YAML style for improved human readability. The project appears to have ceased active development around 9 years ago, suggesting it is no longer actively maintained and may have compatibility issues with modern JavaScript environments.
