ConvertFrom-Json
Converts a JSON-formatted string to a custom object. PowerShell reference
From the PowerShell reference 1 parameter
What it does
Converts a JSON-formatted string to a custom object. The ConvertFrom-Json cmdlet converts a JavaScript Object Notation (JSON) formatted string to a custom PSObject or Hashtable object that has a property for each field in the JSON string. JSON is commonly used by web sites to provide a textual representation of objects. The cmdlet adds the properties to the new object as it processes each line of the JSON string. The JSON standard allows duplicate key names, which are prohibited in PSObject and Hashtable types. For example, if the JSON string contains duplicate keys, only the last key is used by this cmdlet. See other examples below. To generate a JSON string from any object, use the ConvertTo-Json cmdlet. This cmdlet was introduced in PowerShell 3.0. NOTE: In Windows PowerShell 5.1, ConvertFrom-Json returns an error when it encounters a JSON comment. In PowerShell 6 and higher, the cmdlet supports JSON with comments. JSON comments aren't captured in the objects output by the cmdlet. For more information, see the _JSON comments_ section of the about_Comments article.
