Worked on enhancing Excel data ingestion for the apache/seatunnel repository by developing improvements to the LocalFile source connector. Introduced an excel_engine option, enabling users to switch between POI and EasyExcel for Excel file parsing, which addressed memory overflow risks when handling large datasets. Updated date and time parsing utilities to support additional Excel formats, improving compatibility and reliability. Focused on Connector Development and Data Processing using Java, with an emphasis on robust file handling and Excel parsing. These changes increased scalability and performance for large workbooks, supporting more efficient downstream analytics and expanding format support within the connector framework.
