Frequently Asked Questions
Will this validate my HTML?
No — js-beautify only formats, it doesn't validate. For HTML validation, use the W3C Markup Validation Service.
What is the difference between HTML formatter and HTML stripper?
The formatter preserves all HTML and adds indentation. The HTML stripper removes tags and extracts only the text content.
Does this handle inline scripts and styles?
Yes. js-beautify formats embedded <script> and <style> blocks with JavaScript and CSS formatting respectively.
