Extract text from Voxel models and tests (QB)
To convert QB Files to another format, you need Minddesk Qubicle or other 3D software.
To convert other file formats to the "Voxel Model File" file type, you need software like Minddesk Qubicle or a similar tool.
The .QB file format serves multiple distinct purposes, making it notoriously difficult to handle without the correct software. Primarily, it functions as a Qubicle Voxel Model file created by Minddesk Qubicle. Game developers and 3D artists use this format to store volumetric pixels (voxels) for blocky, retro-style graphics popular in indie games. Alternatively, a .QB file can be an ExamView Question Bank containing test questions in an XML-based structure, managed by Echo360's ExamView. Other variations include compiled game scripts for the classic Neversoft Tony Hawk's game engine, or zipped digital whiteboard session files from MURAL and ViewSonic myViewBoard.
The main disadvantage of the .QB format is its extreme fragmentation. A voxel model, an XML question bank, and a compiled game script share the same extension but have absolutely nothing in common internally. Furthermore, these are proprietary formats locked to specific, often expensive or obsolete software. For instance, you cannot easily preview a Qubicle model in a web browser, and ExamView requires specific educational licenses.
To make the data usable elsewhere, you must convert it. Voxel models should be exported to standard 3D formats like OBJ, DAE (Collada), or FBX. During this conversion, you might lose specific Qubicle hierarchy data, but the core geometry and vertex colors usually survive. For ExamView files, exporting to RTF, PDF, or CSV is recommended for sharing tests with students or importing into modern Learning Management Systems (LMS) like Canvas or Moodle.
Because a .QB file can contain binary 3D data, structured XML text, or compiled game code, it is very difficult for standard online tools to open or convert it. Often, only the original software can properly read or export the data. However, you can use convert.guru. Just drag and drop your file to identify the format, view it, and convert it when possible. Our analyzer will check the file headers - whether it is a ZIP archive for a whiteboard session, an XML tree for a test, or a binary voxel matrix - and reveal its true internal content.
Convert.Guru analyzes your QB file, detects the exact format, and lets you read the text inside.
Users also converted !QB, QBX, QBO, LUA, XLSX, QBB, TXT, ZIP, FMF, CMBL, ESX and OX files.
If you want to convert QB file to QBO, ESX, QBX, OX, XLS, XLSX, XLSM, XLSB, ODS, CSV, TSV or TAB, you can use Minddesk Qubicle or similar software from the "Voxel Models & Question Banks" category. In the File menu, look for Save As… or Export….
To convert WQ1, XLSM, NOTES, QPW, WK3, WB2, WKS, XLSB, 123, XLS, WB1 or XLSX files to QB, try Minddesk Qubicle or another comparable tool in the "Voxel Models & Question Banks" 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 QB converter.
