Extract text from Word add-ins (WLL)
To convert WLL add-ins to another format, you need Microsoft Word or other Plugin software.
To convert other file formats to the "Word Add-in / Game Asset" file type, you need software like Microsoft Word or a similar tool.
A .WLL file is most commonly a Microsoft Word Add-in Library or a The Sims Wall Pattern. When used by Microsoft Word, it functions as a compiled executable (sharing the internal structure of a standard Windows DLL or EXE) designed to add custom toolbars, macros, and extended features to the word processor. Alternatively, in the classic game The Sims by Maxis, it stores proprietary 2D texture data for customizable walls.
Because a Word .WLL file contains compiled binary code rather than readable text, it cannot be simply opened as a document. These files pose significant disadvantages today: they are often highly outdated (built for Word 97/2000), lack cross-platform support (Windows only), and are notorious security risks since they can carry macro viruses. Modern web browsers and antivirus software routinely flag or block them. Similarly, The Sims wall patterns are locked into an ancient, closed game-engine format requiring legacy software like HomeCrafter to view or edit.
Converting these files into standard formats is highly restrictive. You cannot mathematically convert a binary executable add-in to a text document like DOCX or PDF. Standard online converters will immediately fail to process a .WLL file because they do not know how to handle proprietary binaries or closed game data archives. Just drag and drop your file onto convert.guru to see what it is and convert it if supported. Our tool will securely inspect its internal hex data and attempt to extract embedded resources. If our analysis detects an underlying texture or icon string, viewing or extraction may still be possible.
Convert.Guru analyzes your WLL file, detects the exact format, and lets you read the text inside.
Users also converted PACKAGE, CHEAT and SKNPRJ files.
If you want to convert WLL file to DLL, SO, DYLIB, BUNDLE, PLUGIN, XPI, CRX, SAFARIEXTZ, APPEX, KEXT, SYS or DRV, you can use Microsoft Word or similar software from the "Software Plugin or Game Asset" category. In the File menu, look for Save As… or Export….
To convert LV2, DYLIB, VST, AAX, DRV, TDE, LADSPA, BUNDLE, AU, DLL, RTAS or SO files to WLL, try Microsoft Word or another comparable tool in the "Software Plugin or Game Asset" 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 WLL converter.
