Extract text from Universal format files (UFF)
To convert UFF files to another format, you need Siemens Simcenter Testlab or other Data software.
To convert other file formats to the "Engineering & Machine Learning" file type, you need software like Siemens Simcenter Testlab or a similar tool.
The .uff file extension represents several highly specialized and often conflicting data formats. The most common variant is the SDRC Universal File Format, used to store experimental structural dynamics and vibration test data. Originally developed by the Structural Dynamics Research Corporation, these files are plain text (ASCII) structures used to exchange engineering data between platforms like Siemens Simcenter Testlab. Another major use is the Universal Framework Format (.uff), a deprecated machine learning model format used by NVIDIA TensorRT to freeze TensorFlow neural network graphs for inference. You might also encounter .uff files as 1C:Enterprise database exchange archives (which are technically ZIP files) or medical Ultrasound File Format data (structured as HDF5 files).
The main problem with .uff files is fragmentation and obsolescence. Identifying what a .uff file actually contains is impossible without analyzing its internal headers. The SDRC text files rely on legacy 'dataset' block structures that require expensive engineering software or custom parsing scripts to read. Meanwhile, NVIDIA's TensorRT UFF format is officially deprecated, meaning older machine learning models will fail to load on modern AI stacks. The 1C:Enterprise files are completely locked into regional ERP systems unless manually extracted.
To make this data usable, conversion is heavily recommended. For SDRC engineering data, convert the text blocks to CSV or MAT (MATLAB) to analyze the frequency data in standard spreadsheet tools. For legacy NVIDIA models, convert to .ONNX to guarantee compatibility with modern deep learning frameworks. For 1C:Enterprise data, extracting the underlying XML files is required for database migration. Drop your file here to view and convert it securely right in your browser.
Convert.Guru analyzes your UFF file, detects the exact format, and lets you read the text inside.
Users also converted UDF, SSP, TFA and LFS files.
If you want to convert UFF file to , you can use Siemens Simcenter Testlab or similar software from the "Experimental Dynamics Test Data" category. In the File menu, look for Save As… or Export….
To convert files to UFF, try Siemens Simcenter Testlab or another comparable tool in the "Experimental Dynamics Test Data" 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 UFF converter.
