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(Atlassian should improve the documentation and stop using outdated extensions like syntaxhighlighter)

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

* JSON brush for confluence syntaxhighlighter
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)

Thanks a lot @Robert Galovic  this is very useful.

Can't believe this is still not a native feature of confluence.

One improvement, change

{ regex: /[^\D](\d?\.?\d+)/gm, css: 'constants' },


{ regex: /-?(0|[1-9]\d*)(\.\d+)?([eE][+-]?\d+)?/gm, css: 'constants' },

 This will allow to highlight numbers followed by a comma.

Best regards.

This worked but only when I preview a page. If I try to access a saved page normally I get an alert dialog "Can't find brush for: json"

I don't know what you did or how your rights are set, but my suggested solution works not only in preview mode (that would make no sense to me at all, right?).

Even though this question is quite old, for Confluence Cloud you can give our app Prism Syntax Highlighter for Confluence (see a try.

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