title: How to Treat "null" Values in JSON file as null with Nodejs
body: <p>I have a large JSON file that is generated by another process that I can't modify. In case of blank values, that process puts "null" as a value of those properties.</p>
  
  <p>And I need to treat these "null" values as null in my <strong>Nodejs</strong> server side, or else they are taken as literal string. I would like to see if there is a way with <code>JSON.parser(fs.readFileSync('...'))</code> to read the file and create a local variable that has <code>null</code> instead of <code>"null"</code> for those properties.</p>
