What is YAML → .env?

A YAML→.env converter that flattens nested objects and arrays into flat KEY=VALUE pairs suitable for dotenv-style config.

How it works

The YAML is parsed, then walked recursively: object keys nest with '__', array indexes become numeric suffixes, and scalars stringify to values.
