• Added CSV format support: Full support for processing CSV files from S3 buckets.

  • Streaming CSV processing using Go's builtin encoding/csv package with memory usage bounded independently of file size

  • Dual output modes: CSV (preserves original formatting) or JSON (converts to structured objects)

  • Comprehensive CSV configuration options:

    • Header row handling (with/without headers)

    • Custom delimiters (comma, semicolon, tab, or custom)

    • Text encoding support (UTF-8, UTF-16, ISO-8859-1, Windows-1252)

    • Advanced parsing options (trimLeadingSpace, lazyQuotes, fieldsPerRecord, comment character)

  • Auto-detection: CSV files with .csv extension are automatically detected when format is set to "auto"
