EBCDIC File Converter

Converts EBCDIC-encoded data to ASCII or UTF-8 to support modern analytics and data integration workflows. It is intended for data engineers, migration teams, and mainframe operations staff who export legacy datasets for loading into data lakes or warehouses.
Conceptually, the converter uses code-page specific mappings to translate each input byte to its Unicode equivalent, then encodes to the chosen target. It supports IBM code pages such as IBM-037 and IBM-1047 and can be extended with additional mappings. The process preserves byte boundaries and can handle fixed-width COBOL data.
Key features include batch processing, option flags for unmapped bytes, and a structured result that includes input and output byte counts, along with a list of unmapped positions if requested. The tool validates inputs, reports unsupported code pages, and avoids parsing file formats beyond encoding translation.
Use cases include migrating customer records, log files, and transaction data from legacy systems to modern data platforms. The solution improves data integrity, reduces manual re-encoding errors, and aligns with governance requirements by providing traceable conversion outputs.
