A JSON text is a sequence of tokens formed from Unicode code points that conforms to the JSON value grammar. The set of tokens includes six structural tokens, strings, numbers, and three literal name tokens.
The six structural tokens:
[ U+005B left square bracket
{ U+007B left curly bracket
] U+005D right square bracket
} U+007D right curly bracket
: U+003A colon
, U+002C comma
These are the three literal name tokens:
true U+0074 U+0072 U+0075 U+0065
false U+0066 U+0061 U+006C U+0073 U+0065
null U+006E U+0075 U+006C U+006C
Insignificant whitespace is allowed before or after any token. Whitespace is any sequence of one or more of the following code points: character tabulation (U+0009), line feed (U+000A), carriage return (U+000D), and space (U+0020). Whitespace is not allowed within any token, except that space is allowed in strings.
