Converting plain text data to json

Question

I have some data that I am trying to process with javascript.

DATA:
A.         Category one
1.          item one 
2.          item two
B.         Category two
3.          item three
4.          item four
C.         Category three
5.          item five
6.          item six

DESIRED OUTPUT:
[{
"Category one":["item one", "item two"],
"Category two":["item three", "item four"],
"Category three":["item five", "item six"]
}]

Is there a library that will help me with text parsing in javascript?

THIS IS AS FAR AS I GOT:

function parseFormat(str) {
var arr = [];
str.split('\n').forEach(function (line) {
    var obj = {};
     line.split('.').forEach(function (item) {
        if (isNaN(item)) {
            // ??
        } else {

        }
    });
    return ?;
});
}

Help? Thanks

Here is the complete function. Please have a look at the code below.

Function to parse the string

function parseFormat(strArg) {
  var
    category,
    output = {},  // Output
    str = strArg.trim();  // Remove unwanted space before processing

  str.split('\n').forEach(function(line) {
    var item = line.split('.');
    if (item[0].match(/\d/)) {  // Match a decimal number
        // Remove unwanted space & push
        output[category].push(item[1].trim());
    } else if (item[0].match(/\D/)) {  // Match UPPERCASE alphabet
        // Remove unwanted space
        category = item[1].trim();
        output[category] = []
      }
    });
  return output;
}

Input string

// ES6 Template Strings to define multiline string
var str = `
  A.         Category one
  1.          item one
  2.          item two
  B.         Category two
  3.          item three
  4.          item four
  C.         Category three
  5.          item five
  6.          item six
`;

Function call

// Final output Array
var finalOutput = [];
// Parse input string
var parseStr = parseFormat(str);

finalOutput.push(parseStr);

// Desired JSON output
console.log(JSON.stringify(finalOutput));

You can look at the Browser Console for the desired JSON output.

Hope it helps!
