Convert a file to OCC

To convert other file formats to the "Test Automation Container" file type, you need software like OMICRON Test Universe or a similar tool.

About OCC files

The .OCC file extension primarily identifies an OMICRON Control Center document, the standard container format used by electrical engineers for testing protection relays and measuring devices. These files are built on the Microsoft Compound File structure and encapsulate complex test workflows, hardware configurations, and results generated by the OMICRON Test Universe software.

The biggest obstacle for .OCC files is their strict proprietary lock-in. They are effectively "black boxes" that cannot be opened, viewed, or parsed without a licensed installation of the OMICRON suite, which poses a significant hurdle for sharing results with clients or auditors who do not own the software.

Best Conversion Targets:

For Reporting: Since direct viewing is restricted, the most practical solution is to export the internal report generation results to PDF. This ensures the test data is readable by anyone.
For Data Analysis: To analyze test results outside the OMICRON environment, users should export raw data tables to CSV, XML, or XLS (Microsoft Excel).
For 3D Scanning (Secondary Use): If the file comes from an Occipital Structure Sensor, it contains raw 3D recording data. These must be processed and converted into standard mesh formats like OBJ, PLY, or STL to be usable in modeling software like Blender or for 3D printing.

Convert.Guru analyzes your OCC file, detects the exact format, and lets you read the text inside.

Users also converted OGG, PDF, MP4, PNG, IXL, MDB and 2 files.

The OCC Converter Story

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 OCC converter.
