Your best bet is to choose "Javascript" from the syntax highlighting option. Otherwise you can install a custom SyntaxHighlighter brush like this one:

This doesn't work for SyntaxHighlighter in the confluence code makro.

(Atlassian should improve the documentation and stop using outdated extensions like syntaxhighlighter)

You could use JSON Viewer Macro for Confluence (Cloud & Server) 

You can use Code Syntax Highlighter plugin for Confluence cloud, which supports JSON.

Use this brush for JSON, save it as a file and add it via confluence code macro. Have fun ;-)

SyntaxHighlighter.brushes.JSON = function()
var key_bool = 'true false null NULL';
this.regexList = [
{ regex: new RegExp(this.getKeywords(key_bool), 'gm'), css: 'value' },
{ regex: /[^\D](\d?\.?\d+)/gm, css: 'constants' },
{ regex: /((\"[\w]+\S*[^\\]\"))(?=[\:]|\s\:)/gm, css: 'variable' },
{ regex: SyntaxHighlighter.regexLib.doubleQuotedString, css: 'string' },
{ regex: /((\'[\w]+\S*[^\\]\'))(?=[\:]|\s\:)/gm, css: 'comments' },
{ regex: SyntaxHighlighter.regexLib.singleQuotedString, css: 'comments' },
SyntaxHighlighter.brushes.JSON.prototype = new SyntaxHighlighter.Highlighter();
SyntaxHighlighter.brushes.JSON.aliases = ['json', 'Json', 'JSON'];

(If you like, you can customize it by changing the css definitions. Single quoted JSON entries wont comply to the standard, so I used "comments" css on them to mark them for being able later on to correct them easily)
