pdf2json：如何自定义输出json文件？

Question

我可以自定义pdf2json命令行实用程序的输出，以便输出json文件具有特定的结构吗？

我正在尝试从pdf中提取数据（请参见下图）并将其存储为json文件。

我试过了pdf2json -f [input directory or pdf file]。该命令输出一个包含我需要的信息的json文件，但它也包含了许多我不需要的信息：

我只需要pdf文件中的文字。我不需要任何有关格式的信息。所以我需要这样的东西：

{"data":
    {
    "abundant": {
        "positive":1,
        "negative":0,
        "anger":0,
        ...
        },
    "abuse": {...},
    "abutment": {...},
    ...
    }
}

我构建了一个Node.js模块，该模块使用pdf2json和一些简单的数学运算来从PDF中提取表格数据。输出是一个行数组。
