Extract text from ZK user interface files (ZUL)
To convert ZUL UI files to another format, you need ZK Framework or other Developer software.
To convert other file formats to the "UI Markup Language File" file type, you need software like ZK Framework or a similar tool.
The .zul file extension represents a ZK User Interface Markup Language file. It is an XML-based format developed by Potix Corporation for the ZK Java Web Framework. Developers use these files to design rich graphical user interfaces (GUIs) for enterprise web and mobile applications from the server side, typically without needing to write custom JavaScript.
The primary disadvantage of a .ZUL file is its strict dependency on the ZK framework ecosystem. It is essentially useless outside of a Java EE environment running the ZK engine. Standard web browsers cannot render .zul tags directly; a web server must intercept the file and compile the custom tags into standard HTML, CSS, and JavaScript before the client ever sees the page. Furthermore, sharing these files with non-developers causes confusion since they require a code editor or IDE to open, and they look like complex machine code to untrained eyes.
If you need to review the code outside the framework, you must convert the file to a standard text-based format. The best conversion targets are XML (since ZUL is structurally pure XML) or TXT for basic reading. To see the actual rendered UI layout, developers must deploy the code and export the resulting browser view to HTML or PDF.
Converting specialized framework markup is inherently difficult because standard online converters fail to interpret custom Java UI tags. You usually need the original development environment to properly render or export the data.
Convert.Guru analyzes your ZUL file, detects the exact format, and lets you read the text inside.
Users also converted HTML files.
If you want to convert ZUL file to HTML, HTM, CSS, JS, PHP, ASP, ASPX, JSP, JSPX, PY, RB or PL, you can use ZK Framework or similar software from the "Web UI Definition" category. In the File menu, look for Save As… or Export….
To convert RSS, CSS, CGI, SITEMAP, PL, WEBMANIFEST, JSON, JS, XML, HTML, ICO or HTM files to ZUL, try ZK Framework or another comparable tool in the "Web UI Definition" category.
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 ZUL converter.
