账本数据库是db3，点击导入没反应

[MuskCheng]

我的账本数据库是db3，用了gpt返回的代码，粘贴完了之后方案选择直接变成了空白，然后点击导入没反应
账单文件目前是487KB

[glink25]

@MUskby 可否提供去除隐私后的db3账单文件供调试呢？可以发送到下面这个邮箱 centnext@icloud.com

[MuskCheng]

您好，已发送，感谢

[glink25]

@MUskby db3无法一次性在浏览器中解析完成，因此我分步骤让大模型进行解析：

1，首先让大模型将db3文件转为json，你可以使用这个demo进行转换，并且下载转换后的json

2，考虑到转换后的文件较大，因此先将json的数据格式解析为typescript，便于大模型理解，然后将该类型作为提示词代替较大的json文件喂给大模型，让其输出最终的转换方案。

3，大模型最终给出了可用的脚本，我检查了一下，将该脚本和转换后的json文件导入到Cent后，可以识别出来大部分账目，不过分类可能需要你重新修改一下

这是大模型给出的转换脚本，希望对你有帮助，你也可以按照上面的步骤重新要求大模型生成新的脚本，让结果更符合你的需求：

async function transform(file, ctx) {
/**
* 设计原则：let-it-crash —— 遇到无法解析或严重不一致的数据应抛出错误以便上层处理。
*
* 支持：
* - JSON 导出（优先）
* - CSV（尝试使用 ctx.Papa 解析）
* - Excel (.xlsx/.xls)（使用 ctx.XLSX 解析）
*
* 返回 ExportedJSON 结构：{ items: Full<Bill>[], meta: GlobalMeta }
