jq transform - json child array to delimited string












2














i want to transform the following input with jq



{
"count": 1000,
"rows": [{
"id": 1,
"child_id": 11,
"childarray": ["value1", "value2"]
},
{
"id": 2,
"child_id": 12,
"childarray": ["value3", "value4"]
}
]
}


Output should be:



[
{
"id": 1,
"child_id": 11,
"childarray": "value1, value2"
},
{
"id": 2,
"child_id": 12,
"childarray": "value3, value4"
}
]


I use this jq filter-> "[.rows]" but don't know howto "join" the array -> "childarray": ["value1", "value2"] to a comma delimited string -> "value1, value2"

          map + join approach:



          jq '.rows | map(.childarray |= join(", "))' input.json


          The output:



          [
          {
          "id": 1,
          "child_id": 11,
          "childarray": "value1, value2"
          },
          {
          "id": 2,
          "child_id": 12,
          "childarray": "value3, value4"
          }
          ]




          Another alternative is:



          jq '.rows.childarray |= join(", ") | .rows'
