In everyday use, formats such as JSON transmit data from your organization’s server. This is sent to applications used by internal departments, like Accounts or HR. XML, JSON, and other formats deliver information which is read by individual machines. This is then converted to usable information for employees.
JSON is built upon two universal data structures. One is a collection of name/value pairs, which is known as an object in JSON. The other is an ordered list of values, which in JSON is known as an array.
