What is HTML Formatter?
An HTML formatter transforms unformatted or single-line HTML into cleanly indented markup with proper nesting, line breaks, and consistent indentation. It recognizes HTML elements, self-closing tags (br, img, input, etc.), and nesting levels to produce visually clear code structure. Properly formatted HTML is easier to read, debug, and maintain. It helps developers quickly identify nesting errors, missing closing tags, and structural issues. The formatter processes the HTML in a single pass, tracking indent levels as tags open and close, producing clean output that follows common HTML coding conventions.
