Text document to JSON data Using JavaScript or Nodejs

How to convert the text document data to JSON, I have a text file that should be parsed to JSON data. I had attached the data present in a text document below, the data in the text contains many blank spaces. How to construct a proper JSON... I'm not able to get any solution on how to do this, can anyone help me out either on javascript or nodejs.
