Use JSON2.js

var obj = JSON.parse(data);
for(var key in obj){
    if (obj.hasOwnProperty(key)){
        var value=obj[key];
        // work with key and value
    }
}

Use for-in...something like:

for (var i in dictionary) {
    dictionary[i].forEach(function(elem, index) {
        console.log(elem, index);
    });
}

where the i would iterate through your dictionary object, and then you can use forEach for every json array in the dictionary(using dictionary[i])

With this code you'll get

Object {id: "0", name: "ABC"} 0 
Object {id: "1", name: "DEF"} 1 
Object {id: "0", name: "PQR"} 0 
Object {id: "1", name: "xyz"} 1 

You can tailor the forEach function definition(replacing the console.log bit) to do whatever you want with it.

DEMO

Edit: Doing the same thing using Object.keys

Object.keys(dictionary).forEach(function(key) {
    dictionary[key].forEach(function(elem, index) {
        console.log(elem, index);
    });
});

Edit2: Given the somewhat complicated structure of your jsonData object, you could try using a (sort of) all-purpose function that would act on each type of component separately. I've probably missed a few cases, but maybe something like:

function strung(arg) {
    var ret = '';
    if (arg instanceof Array) {
        arg.forEach(function(elem, index) {
            ret += strung(elem) + ',';
        });
    } else if (arg instanceof Object) {
        Object.keys(arg).forEach(function(key) {
            ret += key + ': /' + strung(arg[key]) + '/';
        });
    } else if (typeof arg === "string" || typeof arg === "number") {
        ret = arg;
    }
    return ret;
}

document.body.innerHTML = strung(jsonData);

DEMO

Of course that I cant make an entire project solution for you but the function that you wanted must have this kind of logic.

const jsonData = [{
  "squadName": "Super hero squad",
  "homeTown": "Metro City",
  "formed": 2016,
  "secretBase": "Super tower",
  "active": true,
  "members": [
    {
      "name": "Molecule Man",
      "age": 29,
      "secretIdentity": "Dan Jukes",
      "powers": [
        "Radiation resistance",
        "Turning tiny",
        "Radiation blast"
      ]
    },
    {
      "authorization": "Black card",
      "location": [
        "Next",
        "Previous",
        "Here"
      ]
    }
  ]
}]

jsonData.forEach(item=>{
  
  item.members.map((member)=>{
    
    if(member.location&&member.location[0]){
  
      //Do whatever, maybe you want to use return statement in there
      console.log(member.location)
    }
    else{
    
      //do something else, or add more conditions
      console.log("There's no location in it")
    }
  })
})

you can put it in a variable and add your variable inside your jsx return statement or use it directly in middle of your function's return statement.

Good luck.

• You want to convert the following Spreadsheet values as follows.

  • From

    Persons name    surname profession
    Sally   Sally   Smith   Developer
    John    John    Appleseed   Accountant
    

  • To

    {
      "ID Sally": {"name": "Sally", "surname": "Smith", "profession": "Developer"},
      "ID John": {"name": "John", "surname": "Appleseed", "profession": "Accountant"}
    }
    

• You want to achieve this using Node.js.

• You have already been able to get the values from Spreadsheet.

  • The values of sheetData in your script is as follows.

    [
      ["Persons","name","surname","profession"],
      ["ID Sally","Sally","Smith","Developer"],
      ["ID John","John","Appleseed","Accountant"]
    ]
    

If my understanding is correct, how about this answer? Please think of this as just one of several possible answers.

Sample script:

var sheetData = [["Persons","name","surname","profession"],["ID Sally","Sally","Smith","Developer"],["ID John","John","Appleseed","Accountant"]];

// Sample script for converting the values from Spreadsheet to a dictionary.
var header = sheetData.shift();
header.shift();
var dictionary = sheetData.reduce(function(obj1, row) {
  var value = row.shift();
    obj1[value] = header.reduce(function(obj2, f, j) {
    obj2[f] = row[j];
    return obj2;
  }, {});
  return obj1;
}, {});
console.log(dictionary);


// Write each dictionary to its own es6 module file
let personArray = [];
for (const person in dictionary) {
    let output = `export const ${person} = {\n`;
    for (const key in dictionary[person]) {
        const value = dictionary[person][key];
        if (value && isNaN(value)) {
            output += `    {value}",\n`;
        } else if (!isNaN(value) && value !== "") {
            output += `    {value},\n`;
        } else {
            output += `    ${key}: undefined,\n`;
        }
    }
    output += `};\n\n`;
    personArray.push(output);
}
console.log(personArray);

• In above sample script, dictionary can be used for dictionary in your script.

If I misunderstood your question and this was not the result you want, I apologize. At that time, can you provide the sample input and output values you expect? By this, I would like to modify it.

var test = [{"name":"aName","lastName":"aLastname"},{"name":"bName","lastName":"bLastname"}];

for (var i = 0; i < test.length; ++i) {
    alert(test[i].name + ", " + test[i].lastName);
}

You have added extra td JSFIDDLE

$.each(result.teams, function (index, value) {
        var row = ['<tr><td>', index, '</td>']; // extra td
        // Add if place is found or not.
        $(this.done).each(function () {
            if (this === true) {
                row = row.concat(['<td>yes</td>']);
            } else {
                row = row.concat(['<td>no</td>']);
            }
        });

        $('.scorestable tbody').append(row.join('') + '</tr>');
    });
