What is an HTML Formatter?
An HTML formatter (often called a “beautifier”) cleans up messy HTML by applying consistent indentation, spacing, and line breaks. It doesn’t change the meaning of your tags—it just rewrites the layout so the markup is easier to read, debug, and maintain.
This is especially helpful when you’re working with copied markup, generated HTML, or long pages where nested elements (like lists, tables, and layouts) become hard to scan. Clean formatting also makes version-control diffs more readable because structural changes stand out more clearly.
