YAML / TOML / INI Converter

Config files are the glue between local tools, CI and services. This converter handles common YAML, TOML and INI shapes, turns them into JSON for inspection, and exports readable config formats again without executing custom tags.

Supports common flat/nested config shapes, sections and scalar values. It intentionally avoids executing YAML tags or complex anchors.
