PRJPCB to TXT Converter

PRJPCB to TXT Conversion Explained

Converting a .PRJPCB file to a .TXT file changes a structured printed circuit board project file into a plain text document. .PRJPCB files are project configuration files created by Altium Designer. They do not contain actual schematic or layout data. Instead, they store project settings, compiler options, and file paths linking to the individual .SchDoc and .PcbDoc files.

People convert .PRJPCB to .TXT to extract project metadata, share file lists, or review configuration settings without requiring an expensive CAD software license. You gain universal readability and easy integration with text-processing scripts. However, you lose the ability to open the project directly in Altium Designer. If you only need to read the settings, this conversion is useful. If you need to compile the PCB project, converting to .TXT will break the workflow.

Typical Tasks and Users

This conversion serves specific technical workflows:

• Hardware Engineers: Extracting a list of all schematic sheets and PCB documents included in a specific project version.
• DevOps and CI/CD Pipelines: Parsing project settings to automate design rule checks (DRC) or output job generation.
• Technical Writers: Documenting project configurations, compiler settings, and output paths for internal wikis.
• Non-CAD Staff: Reviewing project structures or bill of materials (BOM) configurations without installing Altium Designer.

Software & Tool Support

Because .PRJPCB files are fundamentally ASCII text files structured in an INI-style format, many tools can interact with them:

• CAD Software: Altium Designer is the native application for creating and managing .PRJPCB files.
• Text Editors: Notepad++, Visual Studio Code, and Sublime Text can open both .PRJPCB and .TXT files natively.
• Scripting Languages: Python and PowerShell can easily parse the INI structure of a .PRJPCB file to extract specific keys and output them as clean .TXT files.

Pros and Cons of the Conversion

Pros:

• Universal Compatibility: Any operating system or device can open a .TXT file.
• Zero Cost: Viewing the extracted project data does not require an Altium license.
• Scripting Ready: Plain text is easier to feed into generic diff tools, version control systems, and custom parsers.

Cons:

• Loss of Functionality: A .TXT file cannot link schematic and PCB documents together or compile a project.
• Broken File Associations: Changing the format removes the automatic association with Altium Designer.
• Context Loss: Extracting only specific parameters into a text summary discards the strict INI-style formatting required by the CAD software.

Conversion Difficulties & Why Convert.Guru

The main difficulty in converting .PRJPCB to .TXT is separating useful data from configuration noise. A naive conversion simply renames the file extension, leaving the user to read through hundreds of lines of raw INI parameters, GUIDs, and window placement coordinates. Different versions of Altium Designer also introduce new parameters or change the internal structure of the project file.

Convert.Guru handles this conversion by parsing the internal structure of the .PRJPCB file. Instead of just changing the extension, it extracts human-readable project summaries—such as the list of source documents, active output jobs, and core project parameters—into a clean, formatted .TXT file. This eliminates the raw configuration noise and handles character encoding automatically, providing a simple and accurate text extraction.

PRJPCB vs. TXT: What is the better choice?

Which format should you choose?

Choose .PRJPCB when you are actively designing, routing, or compiling a printed circuit board. It is the only format that Altium Designer uses to link your schematics, layouts, and output jobs together.

Choose .TXT when you need to share project settings, document file lists, or feed configuration data into a generic text-processing pipeline. Avoid converting to .TXT if your goal is to migrate the actual circuit board design to another CAD tool; for that, you need to export the individual .SchDoc and .PcbDoc files to formats like ODB++ or Gerber.

Conclusion

Converting .PRJPCB to .TXT makes sense when you need to extract and share Altium project metadata with users or systems that lack CAD software. The biggest limitation to watch for is that the resulting text file is strictly for reading and documentation; it cannot be used to compile or manage the actual PCB design. Convert.Guru is a reliable choice for this exact conversion because it intelligently parses the project file to extract meaningful data, delivering a clean and readable text file without the raw configuration clutter.
