Extract text from Altium multi-board projects (PRJMBD)
To convert PRJMBD multi-board projects to another format, you need Altium Designer or other Cad software.
To convert other file formats to the "PCB Design Project File" file type, you need software like Altium Designer or a similar tool.
A .PRJMBD file is a Multi-board Project file created by Altium Designer. Engineers use it as a master container to link multiple individual printed circuit board (PCB) projects together. This allows designers to verify logical connections, pin swapping, and physical 3D mating between different boards in a complex electronic system.
You need Altium Designer or the Altium 365 cloud platform to open and manage these files. The .PRJMBD format is highly proprietary and requires a very expensive commercial software license to access. A major disadvantage is that the file does not contain the actual schematic or layout data. Instead, it stores relational data, connection matrices, and links to external files. If you do not have the linked sub-project files on your local drive, the .PRJMBD file is essentially useless.
You usually need to convert or export this data into standard formats like PDF for assembly drawings, STEP for 3D mechanical CAD integration, or CSV for Bills of Materials. Standard online converters fail to process this file because they cannot read the proprietary structures and lack access to the referenced local files.
Because this file format is difficult to open or convert, often only the original software can properly export the data.
Convert.Guru analyzes your PRJMBD file, detects the exact format, and lets you read the text inside.

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 PRJMBD converter.
