CRP to TXT Converter

CRP to TXT Conversion Explained

Converting a .CRP file to a .TXT file is a highly destructive, one-way extraction process. .CRP is the proprietary Colossal Raw Package format used by Cities: Skylines to store custom assets, maps, and save games. These files are binary archives containing 3D models, textures, game logic, and metadata.

When you convert .CRP to .TXT, you discard all 3D meshes, textures, and playable game data. The output is a plain text file containing only the extracted metadata, such as the asset name, author details, internal tags, XML/JSON configurations, and dependency lists. People perform this conversion to read hidden file information without launching the game. You gain human readability and searchability, but you lose the actual game asset. If your goal is to edit the 3D model of a building or vehicle, this conversion is a bad idea; you should extract the file to .FBX or .OBJ instead.

Typical Tasks and Users

This conversion is highly specific and serves a niche technical audience:

• Modders and Asset Creators: Extracting internal configuration values or scripts from a .CRP file to study how another creator built an asset.
• Server Admins and City Builders: Generating text-based catalogs of large mod collections to track dependencies and identify conflicts.
• Players Debugging Corrupted Saves: Reading the header data of a broken .CRP save file to find missing assets or error logs that prevent the game from loading.

Software & Tool Support

Because .CRP is a proprietary format developed by Colossal Order, standard archive tools like 7-Zip cannot open it. You need specialized tools to read or extract data from these packages.

• CRP Extraction Tools: Command-line utilities like CRPExtract (free, open-source) can unpack the binary archive. In-game mods like ModTools allow users to dump asset data and scripts while the game is running.
• TXT Editors: Once the metadata or scripts are extracted, you can view the .TXT file in any standard text editor, such as Notepad++ or Visual Studio Code.

Pros and Cons of the Conversion

Pros:

• Transparency: Exposes hidden metadata, author notes, and dependency lists that are otherwise locked inside a binary package.
• Searchability: Allows users to use standard text search tools (like grep) across thousands of asset files to find specific tags or variables.
• Lightweight: The resulting .TXT file is tiny, often just a few kilobytes, making it easy to share on forums for debugging.

Cons:

• Total Data Loss: All visual and playable components (meshes, textures, LODs) are permanently discarded.
• One-Way Process: You cannot convert a .TXT file back into a working .CRP file.
• Formatting Issues: Depending on the extraction method, the resulting text may contain leftover binary garbage characters or lack proper line breaks.

Conversion Difficulties & Why Convert.Guru

The main technical difficulty in converting .CRP to .TXT is parsing the proprietary binary header. A standard text editor will display a .CRP file as unreadable gibberish because the text strings are buried between compiled binary blobs. A naive conversion attempt often results in encoding errors or corrupted text. The conversion pipeline requires a parser that understands the Colossal Raw Package structure, isolates the string arrays and XML/JSON metadata, and safely discards the binary geometry and texture data.

Convert.Guru handles this extraction cleanly. Instead of forcing users to download command-line unpackers or load heavy game mods, Convert.Guru parses the .CRP header on the server. It accurately identifies readable metadata, strips out the binary garbage, and delivers a clean, UTF-8 encoded .TXT file.

CRP vs. TXT: What is the better choice?

Which format should you choose?

You should keep your files as .CRP if you intend to play Cities: Skylines, share assets on the Steam Workshop, or load custom maps. The game engine can only read the binary package format.

You should choose .TXT only if you are debugging a broken asset, documenting your mod library, or trying to read the internal configuration of a file without launching the game. If you want to modify the visual appearance of a Cities: Skylines asset, avoid .TXT entirely and use an extraction tool that outputs 3D formats like .FBX alongside image formats like .PNG.

Conclusion

Converting .CRP to .TXT makes sense only when you need to extract readable metadata, scripts, or dependency lists from a Cities: Skylines package. The biggest limitation to watch for is the complete and permanent loss of all 3D models and textures during the extraction process. For users who need a fast, accurate way to read the internal text of an asset without installing specialized modding tools, Convert.Guru provides a reliable, browser-based solution for this exact conversion.
