Extract text from project files (PJ)
To convert PJ projects to another format, you need MKS Integrity or other Developer software.
To convert other file formats to the "Software Project File" file type, you need software like MKS Integrity or a similar tool.
The .pj file extension is a fragmented format used by several unrelated software applications, meaning it lacks a single universal standard. Primarily, it functions as a source control project file for MKS Integrity (now PTC RV&S). It is also heavily utilized as a configuration project file for LED display signs in LedshowTW, and as a save state file for the Project64 Nintendo 64 emulator. Other niche uses include CNC simulation projects in Nanjing Swansoft SSCNC and secure PDF document containers via Nitro Pro or the La Poste e-letter service.
The main disadvantage of the .pj format is its generic "project" naming convention, which leads to frequent file association errors. Because these are proprietary, closed-ecosystem files, you cannot natively open them in a web browser, and standard office software will fail to read them. A .pj file from an LED sign software cannot be read by a source control system, causing frustration when sharing files across different teams or environments. Users are often locked into paying for or installing the original software just to view basic text or settings.
Converting a .pj file depends entirely on its internal architecture. For example, LedshowTW uses a standard JSON structure under the hood, meaning it is highly recommended to convert these specific files to JSON, TXT, or XML to easily extract the text and display configuration. Conversely, a Project64 save state is a raw binary memory dump, meaning conversion to standard formats is practically impossible without breaking the data.
This format is notoriously difficult to open or convert using generic tools. Standard online converters fail to process it because they cannot guess which specific application created the file. Often, only the original software can properly read or export the data. We can identify the exact file signature, inspect the binary or text content, and extract readable data if an underlying embedded format (like JSON) is detected.
Convert.Guru analyzes your PJ file, detects the exact format, and lets you read the text inside.
Users also converted JDF, XSC, LPI, TWH, BCF, GW and MW files.
If you want to convert PJ file to TWH, BCF, GW or MW, you can use MKS Integrity or similar software from the "Project Configuration Storage" category. In the File menu, look for Save As… or Export….
To convert files to PJ, try MKS Integrity or another comparable tool in the "Project Configuration Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PJ converter.
