BOB to TXT Converter

BOB to TXT Conversion Explained

Converting .BOB (Binary Object Body) files to .TXT (Plain Text) changes compiled game 3D models and binary backups into human-readable text. People convert .BOB to .TXT to inspect, debug, or modify the internal data of a 3D asset without needing the original game engine or specialized 3D modeling software.

When you convert .BOB to .TXT, you gain transparency. You can read vertex coordinates, material paths, and node hierarchies using a standard text editor. However, you lose direct game compatibility. Game engines require binary files for fast loading and rendering. A plain text file cannot be loaded directly into the game without being recompiled back into a binary format. This conversion is a bad idea if you just want to play a game or install a finished mod, but it is essential for reverse engineering.

Typical Tasks and Users

This conversion is highly specific to game development, modding, and data recovery workflows. Common users include:

• Game Modders: Extracting 3D mesh data from legacy space simulators (like the X-series games) to change texture paths or scale values manually.
• Reverse Engineers: Analyzing proprietary binary backups to understand how a specific game engine structures its 3D scene graphs.
• Archivists: Converting undocumented binary models into plain text to ensure the raw coordinate data remains readable decades later.
• Data Miners: Extracting readable strings, such as hidden developer comments or material names, from compiled game assets.

Software & Tool Support

Handling .BOB files usually requires community-built modding tools or hex editors, while .TXT files are universally supported.

• Egosoft Modding Tools: Command-line utilities like X2BC (X2/X3 Bod Compiler) are traditionally used to decompile binary .BOB files into text-based .BOD or .TXT formats.
• Blender: Free 3D software that can import some .BOB files using community-written Python scripts, which can then export the data as text.
• HxD: A free hex editor used to manually inspect the binary structure of a .BOB file before attempting a text extraction.
• Notepad++: A free, robust text editor ideal for opening the massive .TXT files generated by decompiling 3D models.

Pros and Cons of the Conversion

Pros:

• Editability: You can change texture references, node names, or specific vertex coordinates using any basic text editor.
• Version Control: Plain text files can be tracked in Git, allowing developers to see exact line-by-line changes to a 3D model's structure.
• Transparency: Exposes the raw data, making it easier to write custom import scripts for modern 3D software.

Cons:

• File Size: A .TXT representation of a 3D model is often 3 to 10 times larger than the compressed binary .BOB file.
• Broken Compatibility: The game engine will not read the .TXT file. It must be recompiled.
• Syntax Sensitivity: Editing the text file manually is risky. A single missing comma or misaligned bracket can corrupt the entire model structure.

Conversion Difficulties & Why Convert.Guru

The primary technical difficulty when you convert .BOB to .TXT is parsing proprietary binary structures. .BOB files do not use a universal standard; their structure depends entirely on the specific game engine that compiled them. Converting them requires mapping binary floating-point numbers to readable text arrays without losing precision. If the conversion tool rounds the numbers incorrectly, the 3D model will suffer from vertex snapping or distorted geometry when recompiled.

Convert.Guru handles this conversion accurately by safely decoding the binary arrays and extracting the structural data into a clean, formatted text layout. It bypasses the need to configure outdated command-line decompilers, providing a simple way to extract readable coordinates, material strings, and backup metadata directly from your browser.

BOB vs. TXT: What is the better choice?

Which format should you choose?

Keep your files as .BOB if you are actively running the game, testing a mod in-engine, or distributing a finished asset to players. The binary format is required for performance and compatibility.

Convert to .TXT only if you need to inspect the internal data, debug a corrupted backup, or manually edit a string (like a texture file path) without opening a 3D modeling program.

Note: If your goal is to visually edit the 3D geometry, converting to .TXT is the wrong approach. You should convert the .BOB file to a standard 3D format like .OBJ or .FBX instead.

Conclusion

Converting .BOB to .TXT makes sense when you need to reverse-engineer game 3D models or extract readable data from proprietary binary backups. The biggest limitation to watch for is the complete loss of game engine compatibility, as the resulting text file must be recompiled before the game can render it again. For users who need to inspect this data quickly and accurately, Convert.Guru provides a reliable, automated way to extract the binary contents into a clean text format without relying on outdated modding utilities.
