The Legacy Data Format Translator

 Create a Legacy Data Format Translator that converts outdated or proprietary business data into modern, documented formats. Support user-supplied file specifications, fixed-width text, delimited files, XML, JSON, and database exports. Let users define field mappings, encodings, date conventions, numeric formats, nested structures, and transformation rules. Generate conversion pipelines with validation checks, error reports, sample previews, and round-trip comparisons where reversible conversion is possible. Identify records that cannot be converted without losing information and provide a manual exception queue. Preserve original files, document every transformation, and never silently truncate values or guess ambiguous field meanings.
