MCH to TXT Converter

MCH to TXT Conversion Explained

Converting .MCH (Magellan GPS track logs) to .TXT (plain text) changes proprietary, vendor-locked geographic data into a human-readable format. People convert .MCH to .TXT to extract raw coordinates (latitude, longitude, elevation, and timestamps) without needing legacy Magellan software. You gain universal readability and the ability to import data into spreadsheets or custom scripts. However, you lose the native track structure, waypoint icons, and direct compatibility with mapping software. The main trade-off is sacrificing mapping utility for raw data accessibility. If you want to view the route on a map, converting to .TXT is a bad idea; you should convert to GPX or KML instead.

Typical Tasks and Users

• Data Analysts and Researchers: Need to import raw GPS coordinates into Microsoft Excel or R for statistical analysis.
• Legacy Hardware Owners: Users with old Magellan GPS devices (like the Magellan 315/320) who can no longer run outdated software on modern operating systems.
• Software Developers: Writing custom parsers to migrate old track logs into modern spatial databases.
• Archivists: Converting proprietary vendor-locked files into plain text to ensure long-term data preservation.

Software & Tool Support

• Magellan VantagePoint: The official (but legacy) Windows software from Magellan. It can open .MCH files and export the data to standard formats, which can then be saved as text.
• GPSBabel: A free, open-source command-line tool (GPSBabel) that translates between hundreds of GPS formats. It can read Magellan formats and output to tab-separated or comma-separated .TXT.
• GPS Visualizer: A free web-based tool (GPS Visualizer) that accepts various GPS files and outputs plain text tabular data.
• Convert.Guru: A web-based conversion tool (Convert.Guru) that automatically detects the .MCH structure and extracts the raw text data.

Pros and Cons of the Conversion

Pros:

• Universal Compatibility: .TXT files open on any operating system without specialized software.
• Editability: You can manually edit coordinates, fix errors, or delete bad track points using a basic text editor.
• Transparency: The raw data is fully visible, making it easy to audit or parse with custom scripts.
• Legacy Support: Rescues data trapped in an obsolete, proprietary format.

Cons:

• Loss of Mapping Utility: Mapping apps (like Google Earth or Strava) cannot read unstructured .TXT files.
• Fidelity Loss: Metadata such as device settings, datum configurations (like NAD 83), and specific waypoint symbols are usually discarded.
• Structure Issues: The resulting .TXT file requires a strict delimiter (like commas or tabs) to remain useful. If the conversion flattens the data without delimiters, it becomes a useless block of numbers.

Conversion Difficulties & Why Convert.Guru

The main technical problem in converting .MCH to .TXT is parsing the proprietary Magellan encoding. Because .MCH was designed for specific hardware, the coordinate data is often stored in non-standard blocks or relies on legacy datum setups. Standard text editors will display garbled characters if you try to open the file directly. The conversion pipeline must decode the proprietary format, extract the latitude, longitude, elevation, and time values, and map them into a clean, delimited text layout. If the parser fails to recognize the specific Magellan device version, it will output corrupted coordinates.

Convert.Guru handles this conversion accurately by identifying the specific .MCH file signature before extraction. It bypasses the need to install outdated Magellan software and safely extracts the raw coordinate data into a clean, readable .TXT file without injecting formatting errors.

MCH vs. TXT: What is the better choice?

Which format should you choose?

Choose .MCH if you are still actively using a legacy Magellan GPS device and managing your routes with Magellan VantagePoint. Choose .TXT if you need to extract the raw coordinate data for spreadsheet analysis, custom programming, or long-term archiving. However, you should avoid this conversion entirely if your goal is to view the track on a modern map or fitness app. In that case, convert the .MCH file to GPX or KML instead.

Conclusion

Converting .MCH to .TXT makes sense when you need to rescue raw geographic data from an obsolete, proprietary format for analysis or archiving. The biggest limitation to watch for is the complete loss of direct mapping compatibility, as standard navigation apps cannot read plain text files. Convert.Guru is a reliable choice for this exact conversion because it accurately parses the legacy Magellan encoding and delivers clean, structured text without requiring you to install outdated software.
