You can create a temporary parent node, and get the innerHTML content of it:
var el = document.createElement("p");
el.appendChild(document.createTextNode("Test"));
var tmp = document.createElement("div");
tmp.appendChild(el);
console.log(tmp.innerHTML); // <p>Test</p>
EDIT: Please see answer below about outerHTML. el.outerHTML should be all that is needed.

How to Convert Node.js Buffer to String | Toptal®
May 26, 2026 - The Buffer class uses UTF-8 by default when converting to/from strings, but you can also choose another one from a small set of supported encodings: const b = Buffer.from([101, 120, 97, 109, 112, 108, 101]); console.log(b.toString('latin1')); // example · In most cases, UTF-8 is the best option for both reading and writing. Here is the full list of encodings supported by Node.js as of September/2021 (names are not case sensitive):

What you're looking for is 'outerHTML', but we need a fallback because it's not compatible with old browsers.
var getString = (function() {
var DIV = document.createElement("div");
if ('outerHTML' in DIV)
return function(node) {
return node.outerHTML;
};
return function(node) {
var div = DIV.cloneNode();
div.appendChild(node.cloneNode(true));
return div.innerHTML;
};
})();
// getString(el) == "<p>Test</p>"

Using the Buffer `toString()` Function in Node.js - Mastering JS
August 21, 2020 - Node.js supports numerous different encodings for buffers. The most commonly used are: 'utf8' 'hex' 'base64' For example, by calling .toString('hex'), you get a string representation of the buffer where each byte is encoded as 2 hexadecimal characters. const fs = require('fs'); const buf = fs.readFileSync('./package.json'); buf.toString('hex'); // '7b0a2020...'

How to Convert an HTML Node to a String in JavaScript - Actual Wizard
October 5, 2020 - In most cases, you will likely want to use the outerHTML method on the node that your code has selected. OuterHTML includes the tag of the node itself, whereas the innerHTML method does not. ... <!DOCTYPE html> <html lang="en"> <head> <meta content="text/html;charset=utf-8" http-equiv="Content-Type"> <meta content="utf-8" http-equiv="encoding"> <title>Extract HTML with JS - getElementById()</title> </head> <body> <div id="test123"> <ul> <li>Example Element One</li> <li>Example Element Two</li> <li>Example Element Three</li> </ul> </div> <script> var MyNode = document.getElementById("test123"); var MyNodeHTML = MyNode.outerHTML; console.log(MyNodeHTML); </script> </body> </html>

You need node.js for that and this code:
const fs = require('fs')
const fileContents = fs.readFileSync('./myFile').toString()

You need to use Node.js for that. The code would be:
const fs = require('fs');
const fileName = "myFile.txt";
const fileData = fs.readFileSync(fileName, "utf8");

I would recommend using JSON.stringify, which converts the set of the variables in the object to a JSON string.
var obj = {
name: 'myObj'
};
JSON.stringify(obj);
Most modern browsers support this method natively, but for those that don't, you can include a JS version.
