In my angular app, assume I have a string value 00065. I need to convert this to a number and add + 1. i.e; 00065 + 1, which is 00066 Same way if the number is 00120, I should do 00120 +1 which is 00121. I don't want the preceeding zeros not be to ignored. As soon as I convert it to number using Number, the preceeding zeros are removed. how can I acheive this.

Create method 

pad(n) { return ("000000" + n).slice(-6); }

Call this method in ur model.

Convert the string using parseInt, then if you don't need IE support you can use the String.prototype.padStart() method.

For example:

function paddedAddOne(value) {
  const nextValue = parseInt(value, 10) + 1;
  return `${nextValue}`.padStart(5, '0')
}

Otherwise you'll need to add a polyfill.
