Extract text from Cadence journal logs (JRL)
To convert JRL Journal logs to another format, you need Allegro PCB Designer or other Data software.
To convert other file formats to the "Session Journal File" file type, you need software like Allegro PCB Designer or a similar tool.
A .JRL file is primarily a PCB design journal file utilized by Cadence Allegro PCB Designer. It acts as an automated session log, recording every command, coordinate click, and parameter change made by an engineer during a printed circuit board (PCB) design session. This format allows designers to replay complex command sequences, automate repetitive routing tasks, or recover lost work after an unexpected software crash.
However, the .JRL format presents significant challenges outside of its native environment. It is a proprietary macro log tied exclusively to the Cadence ecosystem. Sharing these files with external stakeholders, manufacturers, or non-engineers is ineffective because opening them requires an expensive Electronic Design Automation (EDA) software license. Furthermore, .JRL files cannot be imported into competing EDA tools like Altium Designer or KiCad to migrate layout geometry.
Converting a .JRL file to a standard TXT, LOG, or PDF format is highly recommended for documentation, compliance auditing, or debugging. Converting to a text-based target preserves the human-readable command history, although it strips away the ability to execute the script as an active macro within the Allegro software.
This file format is exceptionally difficult to process because standard online converters fail to recognize Cadence-specific macro syntax. They often misinterpret the file as an unsupported database. Just drag and drop your file to identify the format, view it, and convert it when possible on convert.guru. While it is a closed format, our platform can inspect the internal data structure, extract the embedded plain-text command logs, and help you salvage readable information without needing the original engineering software.
Convert.Guru analyzes your JRL file, detects the exact format, and lets you read the text inside.
Users also converted MCM, ROUT and XLOG files.
If you want to convert JRL file to , you can use Allegro PCB Designer or similar software from the "PCB Design Command Journal" category. In the File menu, look for Save As… or Export….
To convert files to JRL, try Allegro PCB Designer or another comparable tool in the "PCB Design Command Journal" 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 JRL converter.
