Extract text from Cadence journal logs (JRL)
To convert JRL Journal logs to another format, you need Allegro PCB Designer or other Cad software.
To convert other file formats to the "Session Log File" file type, you need software like Allegro PCB Designer or a similar tool.
A .JRL file is predominantly a Cadence Journal File, an automated log generated by Cadence Allegro PCB Designer and related EDA tools. These files serve as a sequential script of every command, keystroke, and coordinate selection made during a design session. While they are critical for the software's "Undo" functionality and crash recovery (allowing users to replay steps), they often cause confusion for non-engineers.
The main downside is that a .JRL file contains instructions, not the actual design data. You cannot view the PCB layout, schematics, or layers just by opening this file; it is merely a text list of commands like add connect or move. Users frequently mistake these for the actual board files (which are BRD), leading to communication breakdowns with manufacturers. Additionally, because they are essentially unformatted ASCII text, they are difficult to read for documentation purposes without cleanup.
To make the data accessible or to debug a design session, the best workflow is to convert the .JRL to standard TXT for universal compatibility with text editors like Notepad++. For archiving project history or sharing a log of design changes with compliance teams, converting to PDF is recommended to ensure the text remains unalterable. If you need to re-run the commands as a macro, keeping it as .JRL or converting to a specific script format supported by the Cadence SKILL language is required.
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 Log" 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 Log" 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.
