PCB to TXT Converter

PCB to TXT Conversion Explained

Converting .PCB to .TXT extracts structured electronic design data into a human-readable plain text format. People convert circuit board designs to text primarily to generate a Bill of Materials (BOM), extract netlists, or export pick-and-place coordinates.

When you convert .PCB to .TXT, you gain universal accessibility. Anyone can open a text file without expensive Electronic Design Automation (EDA) software. However, you lose all graphical layout data, routing paths, 3D models, and native design rules. You trade visual design and manufacturing readiness for raw data extraction.

This conversion is a bad idea if you intend to edit the physical board layout or send the file for fabrication. You cannot easily convert a generic .TXT file back into a working .PCB file.

Typical Tasks and Users

• Hardware Engineers: Extracting a Bill of Materials (BOM) to send to procurement teams for purchasing components.
• Manufacturing Technicians: Generating pick-and-place (XY centroid) data to program automated assembly machines.
• Software Developers: Writing custom Python scripts to parse netlists or component coordinates for automated testing.
• Quality Assurance Teams: Running text-comparison (diff) tools to find component changes between two different board revisions.

Software & Tool Support

The .PCB extension is used by many different, often incompatible, EDA programs. Opening or converting these files usually requires the original software. .TXT files can be opened by any basic text editor.

• Altium Designer: A premium EDA tool that natively creates .PCB files and can export BOMs, netlists, and ASCII text reports.
• KiCad: A free, open-source EDA suite. Its native files are already text-based, but it includes tools to export specific .TXT reports.
• Autodesk Fusion 360: Incorporates EAGLE, which uses .BRD but interacts with legacy .PCB formats and exports text data.
• Notepad++: A free, lightweight text editor for Windows, ideal for viewing large .TXT netlists or BOMs.
• Visual Studio Code: A free code editor useful for developers parsing .TXT outputs with custom scripts.

Pros and Cons of the Conversion

Pros:

• Universal compatibility: Every operating system and device can open a .TXT file instantly.
• Version control: Plain text is easy to track in Git or SVN, allowing engineers to see exactly which components changed.
• Data isolation: It strips away heavy graphical data, leaving only the specific text data (like coordinates or part numbers) needed for a specific task.

Cons:

• Total loss of graphics: A .TXT file contains no visual representation of traces, vias, copper pours, or silkscreen.
• One-way process: You cannot rebuild a complex .PCB file from a generic .TXT BOM or netlist.
• Format fragmentation: A .PCB file from Altium is completely different from a .PCB file from PADS. The resulting text output varies wildly depending on the source software.

Conversion Difficulties & Why Convert.Guru

The main technical problem in this conversion is that .PCB is not a single standard. It is a generic file extension used by dozens of proprietary tools over the last 30 years. Extracting text requires parsing complex binary structures, identifying the correct EDA software origin, and mapping internal databases to readable text. Exporting a BOM requires entirely different logic than exporting a netlist or centroid data.

Convert.Guru simplifies this process. It automatically identifies the underlying .PCB format structure and extracts the most relevant human-readable data. This allows you to access component lists or netlists instantly, without needing to identify the original software, buy expensive EDA licenses, or install heavy desktop applications.

PCB vs. TXT: What is the better choice?

Which format should you choose?

Choose .PCB when you are actively designing, routing traces, or modifying the physical layout of a circuit board. It is the required format for storing the complete engineering design.

Choose .TXT when you need to share a parts list with a purchasing department, feed XY coordinates to an assembly machine, or run a text-comparison between two design versions.

Avoid converting to .TXT if you want to send the board to a manufacturer for physical fabrication. For manufacturing, you should export your .PCB to .GBR (Gerber) and .DRL (Excellon drill) files instead.

Conclusion

Converting .PCB to .TXT makes sense when you need to extract specific text-based data, such as a Bill of Materials or a netlist, from a complex circuit board design. The biggest limitation to watch for is the complete loss of graphical layout and routing data; this is strictly a one-way extraction process. Convert.Guru is a reliable choice for this exact conversion because it handles the proprietary format fragmentation behind the .PCB extension, delivering clean, readable text data without requiring expensive engineering software.
