Json.Stringify Without Quotes on Properties

JSON.stringify key without quotes

It sounds like you are looking for a data-serialization format that is human-readable and version-control-friendly but not as strict about quotes as JSON.

Such formats include:

• Relaxed JSON (RJSON) (simple keys and simple values generally do not require quotes)
• Hjson (simple keys and simple values generally do not require quotes)
• YAML (keys and values generally do not require quotes)
• JavaScript object literal (also printed out by many implementations of "console.dir()" when passed a JavaScript object; simple keys generally not required to be quoted, but string values must be quoted by either single quotes or double quotes)

for completeness:

JSON (requires double-quotes around keys, also called property names, and requires double-quotes around string data values).

JSON.stringify object with keys without the quotes in subobject

Actually what I needed was easily achievable. All I had to do is to add replace to my return statement in the function

return JSON.stringify(file_data).replace(/"(\w+)"\s*:/g, '$1:');

JSON property value without quote

In JSON, double quotes " around values indicate strings. Non-strings are not delimited with "s. Numbers have no delimiters, and the total property getter, when invoked (by JSON.stringify) returns a number, so the resulting JSON does not surround the total value with quotes.

how to create a javascript object without double quotes on the property value

Well I think don't use stringify that solve your problem try it as it is.

JSON Object With or Without Quotes

You are creating a Javascript Object. If you want a JSON-string from it, use JSON.stringify.

So

const myObj = {mykey: "my value"};
const myObjJSON = JSON.stringify(myObj);

Based on comments:
There is no such thing as a JSON Object. There are JSON-strings, which can be parsed to Javascript Objects. Javascript Objects can be stringified to JSON strings. Within a JSON-string keys and values are quoted. So the result of the above is a string containing '{"mykey":"my value"}'.

Try parsing myObjJSON in your browser console (using: JSON.parse(myObjJSON)) and you get: Object {mykey: "my value"}.

There is a regex solution that is simpler but it has a shortcoming that is inherent to regex. For some edge cases in complex and nested objects it does not work.

const data = {a: "b", "b": "c",              c: {a: "b", "c": "d"}}
console.log(stringify(data))
function stringify(obj_from_json){    if(typeof obj_from_json !== "object" || Array.isArray(obj_from_json)){        // not an object, stringify using native function        return JSON.stringify(obj_from_json);    }    // Implements recursive object serialization according to JSON spec    // but without quotes around the keys.    let props = Object        .keys(obj_from_json)        .map(key => `${key}:${stringify(obj_from_json[key])}`)        .join(",");    return `{${props}}`;}

var numbersAsStringsJSON = JSON.stringify(myData, replacer);

function replacer(key, value) {
  if (typeof value === "number") { return String(value); }
  else { return value; }
}
