Ability to nest arrays within value

[Bwarech]

Check out how they do it here:
https://www.npmjs.com/package/csvtojson#from-string
where it says "empowered json parser"

It would be nice to create a structure like this, with nested arrays, using csv elements such as metadata.label[0]...

[
  {
    "file": “sample_doc.docx",
    "metadata": [
      {
        "label": “lob",
        "values": [
          “APV"
        ]
      },
      {
        "label": “state",
        "values": [
          “NY”,”CA"
        ]
      },
      {
        "label": “company",
        "values": [
          “GE”,”GG”,”GI”,”GC”,”CCM-GI”,”CCM-GC"
        ]
      }
    ]
  },
  ...
]
