Transform string of objects into elements of object

I have this below string of objects as shown below.

[0,5]
   0: "A123  G  2323232"
   1: "F345  G  345667"
   2: "T677  G  -34343"
   3: "G454  G  4343"
   4: ""

As you can see "A123 G 2323232" is a string which has tab seperated values in it.

I would like to have a final output as follows. 

[0,4]
   0: 
     UserId:A123
     Type:  G
     Values: 2323232
   1: 
     UserId: F345  
     Type:  G
     Values: 345667
   2: 
     UserId: T677  
     Type:  G
     Values: -34343
   3: 
     UserId: G454  
     Type:  G
     Values: 4343

Please note. the 4th element is empty string. so it should not transform to final data.

Can anyone please suggest how to distribute this to different elements.

You can split each string into its individual pieces of data, and then map those pieces into an object with the properties you want. Here's what it would look like: 

var data = ["A123  G  2323232","F345  G  345667","T677  G  -34343","G454  G  4343", ""];
/* ES6 Syntax */
var objects = data.filter(str => str !== "").map(function (str) {
  var [UserId, Type, Values] = str.split("  ");
  return { UserId, Type, Values };
});

/* ES5 Syntax */
var objectsES5 = data.filter(function (str) {
  return str !== "";
}).map(function (str) {
  var split = str.split("  ");
  return {
    UserId: split[0],
    Type: split[1],
    Values: split[2]
  };
});

console.log(objects);

You could match non space parts and deconstruct the array to the wanted properties and return an object.

var data = ["A123  G  2323232", "F345  G  345667", "T677  G  -34343", "G454  G  4343", ""],
    result = data
        .filter(Boolean)
        .map(s => {
            var [UserId, Type, Values] = s.match(/[^ ]+/g);
            return { UserId, Type, Values };
        });
                
console.log(result);
.as-console-wrapper { max-height: 100% !important; top: 0; }

You can do it using javascript filter() and map() methods like following.

var array = ["A123  G  2323232",
             "F345  G  345667",
             "T677  G  -34343",
             "G454  G  4343",
             ""];

var result = array.filter(function(item) {
  return item.trim();
}).map(function(item) {
  var split = item.split('  ');
  
  return {
    UserId: split[0],
    Type: split[1],
    Values: split[2]
  };
});

console.log(result);

Use a combo of reduce and split:

var strings = [
  "A123	G	2323232",
  "F345	G	345667",
  "T677	G	-34343",
  "G454	G	4343",
  ""
];

var result = strings.reduce(function(res, str) {  // for each string in strings arrays
  var parts = str.split("\t");                    // split the string by tabs
  if(parts.length === 3) {                        // if the string is valid (the splitting yielded 3 parts)
    res.push({                                    // then add an object to the result array using the parts we got
      UserID: parts[0],
      Type: parts[1],
      Values: parts[2]
    });
  }
  return res;
}, []);

console.log(result);
