3rd-Generation Hostess

Convert Excel files into DWH-ready CSV with reproducible templates

An end-to-end workflow that takes any Excel file, performs raw extraction, cleansing, and converts it into structured CSV following a JSON template. As long as the template stays the same, the output schema stays stable even when the source Excel changes - no more 'a column was added' or 'the order changed' incidents in DWH ingestion or BI integration. Supports simultaneous SJIS output.
