将数组转换为JSON(Converting an array into JSON)

 我需要引入一个csv文档并将其转换为JSON，到目前为止，我已经能够将它转换为数组，并从数组中我试图构建一个JSON对象。 
 
 下面是构建JSON的JavaScript，但它不在我需要的结构中，下面是所需结构的示例。 
 
var jsonObj = []; //declare object

for (var i=1;i<csvAsArray.length;i++) { 
  jsonObj.push({key: csvAsArray[i][0]}); //key

    for (var l=1;l<csvAsArray[0].length;l++) { 
      jsonObj.push({label: csvAsArray[0][l], values: csvAsArray[i][l]}); //label + value respectively
    }
}
 
 最终输出要求： 
 
{
  "key": "Sample 01",
  "values": [
    { 
      "label" : "Something" ,
      "value" : 1
    } , 
    { 
      "label" : "Something" ,
      "value" : 2
    }
  ]
},
{
  "key": "Sample 02",
  "values": [
    { 
      "label" : "Something" ,
      "value" : 5
    } , 
    { 
      "label" : "Something" ,
      "value" : 4
    }
  ]
}

I need to bring in a csv doc and convert it to JSON, so far I have been able to convert it to an array and from the array I'm trying to build a JSON object. 
 
Below is the JavaScript that builds the JSON, but its not in the structure I need, underneath is an example of the structure required.
 
var jsonObj = []; //declare object

for (var i=1;i<csvAsArray.length;i++) { 
  jsonObj.push({key: csvAsArray[i][0]}); //key

    for (var l=1;l<csvAsArray[0].length;l++) { 
      jsonObj.push({label: csvAsArray[0][l], values: csvAsArray[i][l]}); //label + value respectively
    }
}
 
Final output required:
 
{
  "key": "Sample 01",
  "values": [
    { 
      "label" : "Something" ,
      "value" : 1
    } , 
    { 
      "label" : "Something" ,
      "value" : 2
    }
  ]
},
{
  "key": "Sample 02",
  "values": [
    { 
      "label" : "Something" ,
      "value" : 5
    } , 
    { 
      "label" : "Something" ,
      "value" : 4
    }
  ]
}
