ConvertFrom-Json and newlines

[MizardX]

Example 3 talks about having to join the lines before converting the JSON file to a PowerShell custom object. This is not necessary, and the description is misleading.

The cmdlet first tries to convert the first item. If it succeeds, it converts the remaining items separately. But if it fails, it joins all the items into a single string, and tries again.

Even if the assumption was true, the better way would be to use the -Raw switch for Get-Content.

All of these works:

• (Get-Content JsonFile.JSON) -join "`n" | ConvertFrom-Json
• Get-Content JsonFile.JSON -Raw | ConvertFrom-Json
• Get-Content JsonFile.JSON | ConvertFrom-Json
• @( '{', '"foo":"bar"', '}' ) | ConvertFrom-Json
• @( '{"foo":"bar"}', '{"foo":"baz"}' ) | ConvertFrom-Json

The example was written prior to PSv5. In PSv5 ConvertFrom-Json changed to work without needing to join lines.
