Convery string to typescript object type

Issue

I need to store chart configuration in DB calling API. Next time I get that config as a string from DB and I need to convert it to object type. For some reason data conversion does not work, and I'm confused why.

The result in console is this:

But actually, result should be like this:

Does someone know some trick on how to convert string to type?

Solution

Finnaly I found the way:

  public covertObjectToJSON(obj: string): JSON {
    obj = obj.replace(/\/\*[\s\S]*?\*\/|\/\/.*/g, '').trim(); // Strip comments
    obj = obj.replace(/'/g, '"'); // Change single quotas with double one
    var jsonStr = obj.replace(/(\w+:)|(\w+ :)/g, function (x) {
      let isNumber: boolean = !isNaN(parseInt(x));
      if (!isNumber)
        return '"' + x.substring(0, x.length - 1) + '":';
      else return x;
    });
    return JSON.parse(jsonStr);
  }
