Convert Lua data to JSON

This EPGP World of Warcraft addon displays the epgp.lua database file.

I wrote a plugin to convert Lua data to a JSON object for display on a guild website. It worked in older versions of the addon, but now I have problems trying to get it to convert the file correctly. Here are two snippets that show the conversion problem - see this demo .

The first works great when forming a nested array:

["roster_info"] = {
    {
        "Agantica", -- [1]
        "ROGUE", -- [2]
        "09/03-2013", -- [3]
    }, -- [1]
    {
        "Intikamim", -- [1]
        "PALADIN", -- [2]
        "17/02-2013", -- [3]
    }, -- [2]
},

becomes

"roster_info" : [
    [
        "Agantica",
        "ROGUE",
        "09/03-2013"
    ],
    [
        "Intikamim",
        "PALADIN",
        "17/02-2013"
    ]
]

But overriding strings sees this next fragment as a nested array when it should be an object inside the array:

["bonus_loot_log"] = {
    {
        ["player"] = "Magebox",
        ["timestamp"] = "2013-03-07 13:44:00",
        ["coinsLeft"] = "-1",
        ["reward"] = "|cffa335ee|Hitem:86815:0:0:0:0:0:0:632235520:90:0:445|h[Attenuating Bracers]|h|r",
    }, -- [1]
            {
        ["player"] = "Lîutasila",
        ["coinsLeft"] = "-1",
        ["timestamp"] = "2013-03-07 13:47:00",
    }, -- [2]
},

becomes

"bonus_loot_log" : [
    [
        "player" : "Magebox",
        "timestamp" : "2013-03-07 13:44:00",
        "coinsLeft" : "-1",
        "reward" : "|cffa335ee|Hitem:86815:0:0:0:0:0:0:632235520:90:0:445|h[Attenuating Bracers]|h|r"
    ],
    [
        "player": "Lîutasila",
        "coinsLeft": "-1",
        "timestamp": "2013-03-07 13:47:00"
    ]
]

Here is a string conversion script that only works with the first fragment.

lua_string
    .replace(/\[(.*)\]\s\=\s/g,'$1:')     // change equal to colon & remove outer brackets
    .replace(/[\t\r\n]/g,'')              // remove tabs & returns
    .replace(/\}\,\s--\s\[\d+\]\}/g,']]') // replace sets ending with a comment with square brackets
    .replace(/\,\s--\s\[\d+\]/g,',')      // remove close subgroup and comment
    .replace(/,(\}|\])/g,'$1')            // remove trailing comma
    .replace(/\}\,\{/g,'],[')             // replace curly bracket set with square brackets
    .replace(/\{\{/g,'[[')                // change double curlies to square brackets
    .replace(/EPGP_DB\s\=/,'');

var str = document.getElementsByTagName('data')[0].innerHTML;
var diff;
do {  // replace curlies around arrays with square brackets
    diff = str.length;
    str = str.replace(/\{(((\n\t*)\t)\S.*(\2.*)*)\,\s--\s\[\d+\]\3\}/g,'[$1$3]');
    diff = diff - str.length;
} while (diff > 0);
str = str
.replace(/EPGP_DB\s=\s/, '')         // remove variable definition
.replace(/\s--\s\[\d+\](\n)/g, '$1') // remove comment
.replace(/\,(\n\t*\})/g, '$1')       // remove trailing comma
.replace(/\[(.*?)\]\s\=\s/g,'$1:')   // change equal to colon, remove brackets
.replace(/[\t\r\n]/g,'');            // remove tabs & returns
console.log(str);
json = window.JSON.parse(str);
console.log(json);
document.getElementById('result').innerText = json.global.last_version;
