About the HTML Beautifier
Scraped pages, exported email templates and minified builds are painful to read. This beautifier puts each element on its own line and indents it by nesting depth so the document structure becomes obvious at a glance.
Void elements, comments and inline script or style blocks are handled correctly, and preformatted content is left alone so whitespace-sensitive markup keeps working.
