A small experimental Java project created to explore Java and basic data processing workflows.
The tool imports data from Excel files (Wingate and InBody tests) and converts them into a unified CSV format used as input for a separate C++ computation prototype. It handles basic parsing, simple validation, and merging of selected metrics.
This project is purely a prototype and learning exercise. Its purpose was to get a first hands-on experience with Java, which I found to be a solid and well-designed language, even though I did not go very deep into it.
The project is not meant for production use, but as a preprocessing step and technical experiment connected to my diploma thesis work, which is mainly developed in Python
Due to GDPR, the original Excel files were removed. The data/input.csv file is the output of this importer, but it is named input because it serves as input for the downstream C++ computation project.
