Description
Server-side infrastructure component responsible for transforming aggregated report data into Bufdir-compliant CSV or Excel files using a library such as exceljs. Column mapping is driven by an external configuration file so the output format can be updated to match Bufdir's current submission requirements without code changes. The generated file is streamed to the client or stored temporarily for async download.
