CAD to TXT Converter

CAD to TXT Conversion Explained

Converting PCB drawings (.CAD) to plain text files (.TXT) is a data extraction process, not a visual translation. When you convert cad to txt, you strip away all visual geometry, copper traces, and board layouts. Only alphanumeric data remains.

People perform this conversion to extract specific text-based manufacturing data, such as a Bill of Materials (BOM), electrical netlists, or pick-and-place machine coordinates. You gain universal machine readability and tiny file sizes. You lose all graphical representation and 2D/3D design data. This conversion is a bad idea if you need to view the board layout or manufacture the physical printed circuit board. For physical manufacturing, you need Gerber or ODB++ files instead.

Typical Tasks and Users

This conversion is essential for hardware manufacturing and supply chain workflows. Common users include electronics engineers, PCB assembly (PCBA) technicians, and procurement managers.

Typical workflows include:

• Component Ordering: Extracting a BOM so purchasing departments can buy resistors, capacitors, and ICs.
• Automated Assembly: Generating XY coordinate files (Centroid data) to program pick-and-place machines.
• Circuit Verification: Exporting netlists to verify electrical connections in simulation software.
• Version Control: Converting binary PCB files to text to track design changes using Git diffs.

Software & Tool Support

Working with Electronic CAD files usually requires specialized Electronic Design Automation (EDA) software, while text files are universally supported.

• CAD Software: Professional tools like Altium Designer, Cadence OrCAD, and Autodesk EAGLE generate and read proprietary PCB files. KiCad is a popular free, open-source alternative.
• TXT Editors: Any basic editor can open the resulting text files, including Notepad++ or Visual Studio Code.
• Command-Line Tools: Once converted to .TXT, data can be parsed using standard CLI utilities like grep, awk, or custom Python scripts.

Pros and Cons of the Conversion

Pros:

• Universal Compatibility: A .TXT file opens on any operating system without requiring expensive EDA software licenses.
• Automation: Plain text is easily parsed by Python scripts, ERP systems, and manufacturing databases.
• File Size: Text files are extremely lightweight, often measuring only a few kilobytes compared to massive PCB project files.

Cons:

• Zero Visual Fidelity: You cannot see the board layout, silkscreen, or component footprints.
• Severe Data Loss: Copper pours, layer stackups, and design rules are completely discarded.
• One-Way Process: You cannot convert a .TXT BOM or netlist back into a functional .CAD PCB drawing.

Conversion Difficulties & Why Convert.Guru

The main technical problem in this conversion is parsing proprietary binary formats. Many older or enterprise PCB .CAD files are closed-source. Extracting text requires reverse-engineering the binary structure or relying on the original software's export engine. If the layout mapping is complex, extracting a clean, tabular BOM or netlist can result in messy, unformatted text. Additionally, poor character encoding handling (e.g., mixing UTF-8 and ANSI) can corrupt special characters in component descriptions.

Convert.Guru handles the parsing of complex EDA structures automatically. It bypasses the need for expensive CAD licenses, safely extracting the relevant alphanumeric data—such as component lists and coordinates—and formatting it into clean, structured .TXT files without encoding errors.

CAD vs. TXT: What is the better choice?

Which format should you choose?

Choose .CAD when you are actively designing the board, routing traces, running electrical rule checks (ERC), or sharing the source project with another hardware engineer.

Choose .TXT when you need to send a component list to a purchasing department, feed XY coordinates to an assembly machine, or run text-based diffs in version control.

Avoid this conversion entirely if you need to send files to a PCB fabricator to etch the physical boards. For that task, you must export your CAD data to standard manufacturing formats like .GBR (Gerber) or .NC (Excellon Drill).

Conclusion

Converting .CAD to .TXT is a highly specific data extraction process that isolates manufacturing text from visual PCB designs. It makes perfect sense for generating BOMs, netlists, and assembly coordinates for supply chains and machines. The biggest limitation to watch for is the absolute, irreversible loss of graphical PCB data. Convert.Guru provides a reliable, fast way to convert cad to txt, ensuring that critical component and coordinate data is cleanly extracted without requiring access to heavy, expensive EDA software.
