GR to TXT Converter

GR to TXT Conversion Explained

Converting a .GR (PCB Boardview) file to a .TXT (Plain Text) file extracts raw schematic data into a human-readable format. This process pulls the netlist, component names, and pin coordinates out of a proprietary boardview file and saves them as plain text.

People perform this conversion to extract a Bill of Materials (BOM), parse netlists with custom scripts, or migrate data to other Electronic Design Automation (EDA) tools. You gain universal readability and the ability to search component data without specialized software. However, you lose all visual layout, graphical traces, and interactive cross-probing capabilities.

If you are a repair technician trying to visually locate a short circuit on a motherboard, this conversion is a bad idea. You trade visual repair utility for raw data accessibility.

Typical Tasks and Users

• Electronics Repair Technicians: Extracting a list of components (BOM) to order replacement parts for a specific motherboard.
• Hardware Reverse Engineers: Dumping netlists to compare circuit paths, document connections, or write custom analysis scripts.
• PCB Designers: Migrating legacy .GR boardview data into modern EDA tools by parsing the raw text data.

Software & Tool Support

You need specialized software to read .GR files, but any basic editor can handle .TXT.

• BoardViewer: The most popular free Windows application for opening and interacting with .GR files.
• OpenBoardView: An open-source alternative for Linux, macOS, and Windows that supports various boardview formats.
• FlexBV: A paid, professional boardview tool that handles .GR files and allows advanced data extraction.
• Text Editors: Tools like Notepad++, VS Code, or Vim are ideal for opening, searching, and editing the resulting .TXT files.

Pros and Cons of the Conversion

Pros:

• Compatibility: A .TXT file opens on any operating system or mobile device without specialized EDA software.
• Scriptability: Raw text exposes the data for Python scripts, grep searches, and version control systems.
• Editability: You can easily modify component values, add repair notes, or format the data into a CSV for spreadsheet use.

Cons:

• Total Fidelity Loss: The text file contains zero graphical representation of the physical printed circuit board.
• No Cross-Probing: You cannot click a pin to highlight where a trace goes across the board.
• Complex Structure: The resulting text is often a massive, unstructured wall of X/Y coordinates and net names that is difficult for humans to read directly.

Conversion Difficulties & Why Convert.Guru

The main technical problem in this conversion is that .GR files are often proprietary, undocumented formats (such as the Great Guo/Rain He format). They are not standardized. Extracting data requires reverse-engineering the specific binary or obfuscated structure of the file. A poor conversion pipeline will corrupt pin mappings, misalign X/Y coordinates, or drop component names entirely.

Convert.Guru is a strong choice for this task because it handles the proprietary decoding automatically. It safely parses the internal netlist and component data, mapping it into a clean, structured .TXT file. You do not need to install legacy Windows software or write custom parsing scripts to get your data.

GR vs. TXT: What is the better choice?

Which format should you choose?

Choose .GR if you are actively probing a motherboard, diagnosing electrical shorts, or need to see the physical location of a component on the PCB.

Choose .TXT if you need to extract a parts list, run a script against the netlist, or document the board's connections in a text-based database.

Avoid this conversion entirely if you expect the text file to retain the visual layout of the board. If you need a shareable visual format for documentation, you should export the .GR file to PDF or PNG instead.

Conclusion

Converting .GR to .TXT makes sense when you need to extract raw netlists and component data from proprietary PCB boardviews for scripting, inventory, or data migration. The biggest limitation to watch for is the complete loss of visual traces and interactive troubleshooting features. Convert.Guru is a reliable choice for this exact conversion because it accurately decodes the undocumented .GR structure and delivers clean, readable text data instantly.
