Converting sections of JSON data into boolean values

Question

Converting sections of JSON data into boolean values

Is there a way to convert certain parts of a JSON string into booleans?

Here is an example of my JSON string:

{
    "file_id": { 
        "width": "560", 
        "height": "270", 
        "esc_button": "1", 
        "overlay_close": "1", 
        "overlay_opacity": "1" 
    }
}

If this were my personal project, I would prefer to convert booleans into true/false strings rather than keeping them as 1 and 0. Since it's not my personal project, I am wondering if there is a way to specify which properties in the JSON string should be treated as booleans. In this example, the booleans would be: esc_button, overlay_close, but not overlay_opacity...

Since this is a JavaScript project, I am curious about what options are available to me and if there is an easy way to achieve this? There are additional settings in this JSON string, but I have only shared a portion of it. The settings vary based on click events

(different file_id === different settings)

EDIT:

I just realized that I could use

parseInt(settings[file_id].esc_button)

to obtain a boolean value, but do I really need to use this method every time? Are there other techniques that I may be unaware of?

JSON is simply a way to format data. When processing JSON data that contains the string "0", you will receive exactly that - the string "0", not the boolean value false.

If the string "0" doesn't fit your program's needs, some data manipulation is necessary.

// for instance
var processData = function(jsonString) {
  var data = JSON.parse(jsonString);
  data.esc_button = (data.esc_button == "1");
  return data;
};

JSON.parse() itself does not have built-in functionality to handle this transformation. It only interprets the data as it appears in the source. If a different interpretation is needed, manual adjustments must be made.

The ideal scenario would be to receive data in a more suitable format from the source. For example, if the data includes actual boolean values, no further conversion would be required.

{
    "file_id": { 
        "width": 560, 
        "height": 270, 
        "esc_button": true, 
        "overlay_close": false, 
        "overlay_opacity": 1 
    }
}

In this case, parsing the JSON directly provides the desired outcome. By removing quotation marks from numerical values like width and height, they are recognized as numbers without the need for conversion. Similarly, boolean values are correctly parsed as true or false, eliminating any confusion.

This approach also eliminates any ambiguity present in the original JSON structure, where both "1" and "1" were used to represent true, despite the latter likely intended to indicate an opacity value ranging from zero to one. With proper formatting, the distinction between these values becomes clear.

JavaScript is known for its dynamic nature, allowing you to make changes on the fly.

if (my_object[its_property]==="1")
   my_object[its_property] = true
else
   my_object[its_property] = false;

A more concise way of achieving this is

my_object=(my_object[its_property]==="1");
