JSON stands for "JavaScript Object Notation", which is a popular lightweight textual format that is used to store object-oriented data in a human-readable form. It comes from JavaScript where it is the native format used to store object information; however, it is commonly used across many programming languages and a popular format for web data exchange. Qt Core supports JSON format, as we'll see in the following code. A simple JSON-formatted definition looks as follows:
{
"name": "Joe",
"age": 14,
"inventory": [
{ "type": "gold", "amount": "144000" },
{ "type": "short_sword", "material": "iron" }
]
}
JSON objects can contain values of the following types:
| Type | Description |
| bool | A boolean value (true or false). |
| double |
