I have some plain machine learnig data set in separate lines like this:

vhigh,vhigh,2,4,small,low,unacc

vhigh,vhigh,2,4,small,med,unacc

vhigh,vhigh,3,more,med,low,unacc

... 1700 more lines like above

I want to convert data into structure like this:

[
  {
    "buying": "vhigh",
    "maint": "vhigh",
    "doors": "2",
    "persons": "2",
    "lug_boot": "small",
    "safety": "low",
    "evaluation": "unacc"
  },
  {
    "buying": "vhigh",
    "maint": "vhigh",
    "doors": "2",
    "persons": "2",
    "lug_boot": "small",
    "safety": "med",
    "evaluation": "unacc"
  },
...

]

and save converted data into new file.json
