Extract text from Expression Web add-ins (XADD)
To convert XADD add-ins to another format, you need Microsoft Expression Web or other Plugin software.
To convert other file formats to the "Software Add-in" file type, you need software like Microsoft Expression Web or a similar tool.
The .XADD file is an add-in package created for Microsoft Expression Web, an HTML editor and web design software that replaced FrontPage. Developers used these files to distribute custom plugins, tools, and extensions to enhance the editor's functionality. The file typically acts as a compressed container that holds interface definitions in XML, logic in JS, and styling in CSS or HTML.
The biggest disadvantage of the .XADD format is its absolute obsolescence. Microsoft abandoned Expression Web in 2012. You cannot open or use this file in modern code editors like Visual Studio Code or modern web browsers. It requires an installed, legacy version of the software running on an older Windows operating system. Because it is an application-specific plugin rather than a standard media or document format, standard online converters completely fail to process it.
Users usually need to convert or extract .XADD files to recover the source code locked inside. The best conversion target is a standard ZIP archive. By extracting the archive, you can recover the embedded web assets. Note that while you keep the code, the plugin itself will not function in any other software.
This file format is difficult to open or convert because it is a closed, proprietary application package. Often only the original software can properly read or execute the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our XADD converter.
