JSON

JavaScript Object Notation (JSON) is a lightweight format used to store and transport data.

JSON is like XML in some respects. It is intended to be both human- and machine-readable. Like XML, JSON is written in plain text.

JSON is a form of serialization. Data can be converted to and from a string that represents that data. Like a Hashtable, JSON-formatted objects are made up of key-value pairs, for example:

PowerShell 3 introduced the ConvertTo-Json and ConvertFrom-Json commands.
