MF4 Converter

About This Tool

The MF4 Converter reads MF4 data files, a common automotive telemetry and test-data format, and outputs widely used data representations such as CSV, JSON, or HDF5. It is designed for data engineers, test engineers, and data scientists who need to analyze telemetry, validation data, or calibration results without manual reformatting.
Conceptually, the tool parses the MF4 structure, collects signals across channels, applies scaling and unit metadata, and aligns time stamps to ensure consistent sampling. Users specify the source file, the desired target format, and optional constraints such as time windows, selected signals, and sampling rate. The backend performs streaming reads when possible to handle large files.
Unique value comes from precise MF4 signal extraction, integrity checks, and native support for multiple outputs, enabling reproducible pipelines. It reduces manual scripting, minimizes conversion errors, and supports automation in CI/CD data workflows for automotive and robotics contexts.
Core features include targeted extraction by channel or signal, time alignment, data type casting, optional endianness handling, on-disk outputs, and metadata generation. Typical use cases cover converting test bench logs to CSV, exporting diagnostic data to JSON, and preparing large datasets for ML or statistical analysis.
