Map Employee CSV Export for Onboarding API
Stratford Manufacturing's HR team exports new hire records weekly from their legacy HRIS as a semicolon-delimited CSV file. Your task is to parse the file, discard employees who are not yet active, and transform the remaining records into the JSON structure required by the Onboarding REST API. The challenge covers CSV format declaration, status-based filtering, field renaming, text normalization, and safe handling of optional columns.
