Convert JSON of arrays to CSV with headers using JQ

Question

I am getting Json as column ID and arrays -

  {
      "ObjectID": [
        0,
        1,
        2,
        3,
        4
      ],
      "Name": [
        "Apple",
        "Orange",
        "Grape",
        "Banana",
        "Jackfruit"
      ],
      "Color": [
        "Red",
        "Orange",
        "Green",
        "Yellow",
        "null"
      ],
      "Acidity": [
        3.9,
        3.5,
        2.99,
        6,
        5.0
      ]
    }

I am trying to convert it using jq to to a plain CSV format like -

ObjectID,Name,Color,Acidity
0,Apple,Red,3.9
1,Orange,Orange,3.5
2,Grape,Green,2.99
3,Banana,Yellow,6
4,Jackfruit,null,5.0

Question related to Export JSON to CSV with Headers using JQ . Looking for preferably a generic answer.

Answer 1

Answering my own question after playing with given answers, generic solution for json arrays

jq --raw-output 'to_entries|map(.key),(map(.value)|transpose[])|@csv'   

Answer 2

A solution using the transpose function:

<file jq -r '(to_entries|map(.key)),([.ObjectID,.Name,.Color,.Acidity]|transpose|.[])|@csv'

The object name is extracted using to_entries|map(.key).

The object content is put inside an array and transposed in order to get arrays with element of each object.

The result is then going through the @csv operator that converts the array into a comma separated string.
