JSON: Array of Objects

See more JSON Examples

Here we have a JSON object that contains an array, where each element in the array is a JSON object. This example demonstrates how to access the objects contained within an array.

{ 
  "employees":[
    {"firstName":"John", "lastName":"Doe"},
    {"firstName":"Anna", "lastName":"Smith"},
    {"firstName":"Peter","lastName":"Jones"}
  ]
}

' This is the above JSON with whitespace chars removed (SPACE, TAB, CR, and LF chars).
' The presence of whitespace chars for pretty-printing makes no difference to the Load
