Syntax

Data types

A JSON file must contain a single JSON value, which can use any of the following five data types: string, number, object, array, and boolean. JSON files can be contained in a single line, however it is often useful to use indentation and line breaks to make a long JSON file more readable.

String

A

Template:Redr, also referred to as a compound, is delimited by opening and closing curly brackets and contains key/value pairs. Pairs are separated with commas, keys and associated values are separated with colons. Each contained key needs to have a name that is unique within the object. A value can be of any data type as well (including another object).

<syntaxhighlight lang="json" line="1"> {

   "Bob": {
       "ID": 1234,
       "lastName": "Ramsay"
   },
   "Alice": {
       "ID": 2345,
       "lastName": "Berg"
   }

} </syntaxhighlight>

Array

Template:Redrs are delimited by opening and closing square brackets and can contain values of any data type, separated by commas. Unlike lists in NBT, values in a JSON array can use different data types.

<syntaxhighlight lang="json"> ["Bob", "Alice", "Carlos", "Eve"] </syntaxhighlight>

Boolean

A

Template:Redr can be either true or false.

<syntaxhighlight lang="json" line="1"> {

   "Steve": {
       "isAlive": true
   },
   "Alex": {
       "isAlive": false
   }

} </syntaxhighlight>
