What is JS to HTML?

JS to HTML conversion is the process of extracting HTML markup from JavaScript code that uses methods like document.write() or document.writeln(). This is often necessary when working with legacy tracking codes, ads, or dynamic content generators.

Our tool automatically parses your JavaScript, identifies string literals within output functions, handles escaped characters, and reconstructs the original HTML structure.
