如何将Minecraft NBT数据转为JS对象/JSON？Chrome为何可解析？

我正在开发一款在线工具，需要将Minecraft通过/data get命令导出的NBT数据字符串转换为原生JavaScript对象或JSON格式。

待转换的NBT数据示例 #

const NbtString =

已实现的解析函数 #

我写了一个parseNBT函数做基础格式修正：

function parseNBT(data) {
    return data
        // Convert "1b", "2b", etc., to plain integers (byte to int)
        .replace(/(\d+)b/g, '$1')

        // Convert "1.0f", "0.2f", etc., to plain numbers (float to number)
        .replace(/(\d*\.?\d+)f/g, '$1')

        // Convert "1.0d", "0.5d" (double) to plain numbers
        .replace(/(\d*\.?\d+)d/g, '$1')

        // Handle "uuid:[I;...]" - Convert to valid JSON array
        .replace(/uuid:\[I;([\d,-]+)\]/g, function (match, p1) {
            return `"uuid": [${p1}]`;
        })
}

遇到的问题 #

处理后的字符串能在Chrome控制台直接解析为对象，但用JSON.parse时会报错，主要问题：

1. 未加引号的键（比如Count、Slot）不符合JSON规范，尤其是值包含冒号的情况（如"the_vault:card"）；
2. 嵌套的JSON字符串（比如config字段的值是转义后的JSON）处理复杂，容易破坏结构。

两个问题请教 #

1. Chrome控制台是怎么实现这种非标准字符串解析的？能不能在代码里复用这个逻辑？
2. 如果不能复用，该怎么修正格式让字符串符合JSON规范，能被JSON.parse正确解析？
