YML File Format

YAML (YML spelling) category

YML is a common alternative extension for YAML files — identical human-friendly structured configuration, just a shorter suffix.

Typical use: Convert .yml files exactly like .yaml — to JSON, TOML or CSV.

About the YML format

YAML は人が読み書きしやすい設定データ形式です。インデントで階層を表し、クラウド、CI、コンテナ設定の標準になりました。

機械が扱うだけなら JSON のほうが安全な場面もあります。設定を人間が触るなら YAML、連携が主なら JSON という判断です。
