PowerShellを使用してJSONをYAMLに変換する

このようなJSONデータがあります。

sample.json

[
  {
    "id": 0,
    "name": "Cofine",
    "title": "laboris minim qui nisi esse amet non",
    "description": "Consequat laborum quis exercitation culpa. Culpa esse sint consectetur deserunt non.",
    "website": "cofine.com",
    "image": "http://placehold.it/32x32",
    "labels": ["blue", "red"],
    "labels_link": ["http://cofine.com/labels/blue","http://cofine.com/labels/red"],
  },
  {
    "id": 1,
    "name": "Zomboid",
    "title": "adipisicing mollit esse aliquip ullamco nisi laboris",
    "description": "Enim consectetur eu commodo officia. Id pariatur proident nostrud occaecat adipisicing voluptate do nisi incididunt id ex commodo.",
    "website": "zomboid.com",
    "image": "http://placehold.it/32x32",
    "labels": ["red"],
    "labels_link": ["http://zomboid.com/labels/red"],
  },
  {
    "id": 2,
    "name": "Sulfax",
    "title": "non minim anim irure nulla ad elit",
    "description": "Pariatur anim officia adipisicing Lorem dolor cillum eu ex veniam sint consequat incididunt. Minim mollit reprehenderit mollit sint laboris consequat.",
    "website": "sulfax.com",
    "image": "http://placehold.it/32x32",
    "labels": ["green", "yellow", "blue"],
    "labels_link": ["http://sulfax.com/labels/green","http://sulfax.com/labels/yellow","http://sulfax.com/labels/blue"],
  }
]

PowerShellを使用してこのjsonデータをyamlに変換するにはどうすればよいですか？各jsonオブジェクトはyamlに変換され、ファイル名がタイトルキープロパティの値である独自のファイルにyamlとして保存されますか？

次のコマンドを実行すると($json | ConvertFrom-Json) | ConvertTo-YAML（ConvertTo-YAML関数はsimpletalk Webサイトから取得されます）、これが出力されます。

    - 'http://sulfax.com/labels/yellow' 
    - 'http://sulfax.com/labels/blue'

ただし、私が探している出力は次のようになります。ファイル名はタイトルキープロパティの値で、ファイルのコンテンツはyamlに変換された対応するjsonオブジェクトです。

Laboris minim qui nisi esse amet non.yaml

他の誰かが答えを探している場合に備えて、私は自分の質問に答えています。

$obj = ($json  | ConvertFrom-Json)

ForEach($item in $obj) {
    $filename = "$($item.title).yaml"
    $item | ConvertTo-YAML > $filename
    "---" >> $filename
}
