During December 2024, this developer enhanced Excel data ingestion for the apache/seatunnel repository by improving the LocalFile source connector. They introduced an excel_engine option, enabling users to switch between POI and EasyExcel for Excel parsing, and updated date and time parsing utilities to support additional formats. By favoring EasyExcel for large datasets, they addressed memory overflow risks inherent to POI, improving both reliability and scalability. Their work focused on Java development, connector design, and file handling, resulting in a more robust and performant workflow for processing large Excel files and expanding compatibility for downstream data analytics tasks.
