I want clean and need proper html format of code. I tried many ways but it's removing all the tags either i want to remove only extra inline styles and extra tags. Sample code i'm placing here. Please help me anyone to achieve this.
Sample Code:

Approach: The jQuery attr() and removeAttr() methods are used to remove the inline style property. The attr() method sets the attribute value to empty (”). Example 1: This example uses attr() method to remove the inline style.
Instead of using inline styles, use external stylesheets. They give you all the benefits of CSS best practices and are easy to use. Employed in this way, all the styles used on your site live in a separate document that is then linked to a web document with a single line of code.
You can remove CSS style properties from an element by setting the property to a null value, e.g. box. style. backgroundColor = null; . When an element's CSS property is set to null , the property is removed from the element.
Given an HTML element and the task is to add and remove multiple classes from it using JQuery. Approach: First select the element to which multiple classes will be added. Then use addClass() method to add multiple classes to the element and removeClass() method to remove multiple classes.
Approach: The jQuery attr () and removeAttr () methods are used to remove the inline style property. The attr () method sets the attribute value to empty (”). Example 1: This example uses attr () method to remove the inline style. using JavaScript/jQuery ? + " the inline style."; down.innerHTML = "Inline style has been removed.";
Now let’s remove styling. An empty string will remove the CSS color property: Don’t do css ("background-color", "none") as it will remove the default styling from the css files. There is another way to remove style. Simply use jQuery removeAttr () method:
Alternatively, you can set the corresponding CSS property to an empty string, which removes it from the element. If you want to remove the style attribute of an element completely, you can use JavaScript’s removeAttribute () method. That’s all about removing inline CSS properties from an element using JavaScript and Query.
Using inline styles means that the styles of the elements are not given by classes or ids but it's specified within the HTML tag using the style="..." attribute. Using this feature of the HTML Cleaner you can easily remove every unwanted inline css code from your document with a single click.
For better readability I have only used few lines of code from what you have added in your question.
If you can use regex to replace style from the html content. Here is a helpful piece of code, you can try this out:
var str = '<span style="color: rgb(34, 34, 34); font-family: sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400;">In 1896 and named after its inventor, </span><a href="https://en.wikipedia.org/wiki/Georges-Fernand_Widal" title="Georges-Fernand Widal" style="color: rgb(11, 0, 128); background-image: none; background-position: initial; background-color: rgb(255, 255, 255); font-family: sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; fot-variant-caps: normal; font-weight: 400;">Georges-Fernand Widal</a>';
ret = str.replace(/style=".*?"/gm,'');
console.log(ret);Anything inside style="..." will be removed by using this.
g in regex is used for global search in given string
m in regex for multi-line search

If you need to Decode the above code as HTML format, you can see below section:
var str = '<span style="color: rgb(34, 34, 34); font-family: sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400;">In 1896 and named after its inventor, </span><a href="https://en.wikipedia.org/wiki/Georges-Fernand_Widal" title="Georges-Fernand Widal" style="color: rgb(11, 0, 128); background-image: none; background-position: initial; background-color: rgb(255, 255, 255); font-family: sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; fot-variant-caps: normal; font-weight: 400;">Georges-Fernand Widal</a>';
ret = str.replace(/style=".*?"/gm, '');
// console.log(ret);
var parser = new DOMParser;
var dom = parser.parseFromString(
'<!doctype html><body>' + ret,
'text/html');
var decodedString = dom.body.textContent;
// console.log(decodedString);
var actualHTML = $('<textarea />').html(decodedString).text();
console.log(actualHTML);<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
