Extract text from CLU files
To convert your CLU file to another format, you need ClustalW or other Game software.
To convert other file formats to the "Game Logic or Bioinformatics" file type, you need software like ClustalW or a similar tool.
The .CLU extension is a classic example of a "filename collision," where multiple unrelated software ecosystems use the same tag for completely different purposes. Most commonly, you are dealing with one of two distinct formats: a compiled Lua script used in the Buzz! quiz game series, or a multiple sequence alignment file generated by ClustalW.
If your file comes from a Buzz! game (developed by Relentless Software for PlayStation), it contains compiled game logic and trivia data. The problem is that these are binary files; opening them in a standard text editor yields unintelligible characters, preventing you from viewing or editing the quiz questions. Users typically look to convert these to TXT or decompiled LUA source code to modify game mechanics or extract assets.
Alternatively, in bioinformatics, a .CLU file stores protein or DNA sequence alignments. While these are technically plain text, they rely on rigid column spacing that typically breaks when opened in processors like Microsoft Word. A single wayward space can render the file useless for downstream analysis. For these users, the goal is usually converting the alignment to a more robust format like FASTA, PHY (Phylip), or NEX (Nexus) for use in phylogenetic tree building software.
Less frequently, .CLU files are found as RIFF container audio clusters in the NovaLogic Delta Force series, requiring extraction to standard WAV files to be playable.
Convert.Guru analyzes your CLU file, detects the exact format, and lets you read the text inside.
Users also converted LUAC, LUC and SCORE files.
If you want to convert CLU file to EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP, MAP, SAV or DAT, you can use ClustalW or similar software from the "Game Script & Alignment Data" category. In the File menu, look for Save As… or Export….
To convert MOD, BIN, CFG, SCX, DAT, MPQ, LOG, CUE, INI, EXE, SCM or ISO files to CLU, try ClustalW or another comparable tool in the "Game Script & Alignment Data" 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 CLU converter.
