I'll begin by reviewing the uploaded files to identify any improper data formatting in the CSV file. After analysis, I've found an issue:

1. **Issue**: Improper Data Formatting in CSV File
   - **Evidence**: The CSV file incorrectly uses semicolons as delimiters instead of commas, which could lead to errors in data loading and interpretation.
   - **Description**: Standard CSV files should use commas to separate data. The existing semicolon delimiters may cause issues during data loading and affect the accuracy of data analysis.

Please inform me if you need more investigation or have any specific questions.
