Extract text from Tcl scripts and Trimble projects (TBC)
To convert TBC scripts and projects to another format, you need TclPro Compiler or other Developer software.
To convert other file formats to the "Compiled Bytecode Script" file type, you need software like TclPro Compiler or a similar tool.
The .tbc file format is primarily used as a Compiled Tcl Bytecode Script, generated by the TclPro Compiler. Developers use this format to execute Tcl applications faster and distribute them without exposing the original source code. Another major use case is for surveying project data files created by Trimble Business Center, and occasionally as tire physics files for the rFactor racing simulator.
The main disadvantage of .tbc files is their compiled and proprietary nature. Tcl bytecode is specifically designed to hide the source code, making it completely unreadable in standard text editors. Trimble survey files are proprietary, often exceed gigabytes in size, and require expensive software licenses to open. Because they lock data inside specific ecosystems, users are heavily restricted and isolated from open-source tools.
Users typically want to decompile Tcl .tbc files back into readable TCL or TXT text scripts to audit the code or fix bugs, though original comments and variable names are usually permanently lost. Trimble users often need to export their data to standard GIS formats like CSV, DXF, or DWG to share coordinates with contractors who do not own the software.
Converting these files is notoriously difficult because they are closed, undocumented binary formats. Standard online converters completely fail to process them because they do not possess the required de-compilation engines or proprietary GIS libraries. Often, only the original software - like the TclPro ByteCode Loader or Trimble Business Center - can properly read or export the exact data structure. However, just drag and drop your file onto convert.guru to identify the format, view it, and convert it when possible. Even with compiled files, our analysis can inspect the internal content, extract raw readable text strings, and detect supported embedded formats to help you recover lost data.
Convert.Guru analyzes your TBC file, detects the exact format, and lets you read the text inside.
Users also converted ZIP, TS4SCRIPT, RPYMC, RPYM and TCL files.
If you want to convert TBC file to TCL, MP4, AVI, MOV, WMV, FLV, WEBM, MKV, M4V, 3GP, OGV or ASF, you can use TclPro Compiler or similar software from the "Compiled Script / Survey Data" category. In the File menu, look for Save As… or Export….
To convert MTS, MOV, RMVB, DIVX, RM, H264, TS, WMV, VOB, MP4, XVID or AVI files to TBC, try TclPro Compiler or another comparable tool in the "Compiled Script / Survey 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 TBC converter.
