public class RowData extends Object
Provides access to all cell data in a single row, indexed by header name or column position.

Used with the mapping-based reader API to support immutable object (e.g., Java record) construction from Excel/CSV rows: 


 ExcelReader.mapping(row -> new PersonRecord(
         row.get("Name").asString(),
         row.get("Age").asInt()
 )).build(inputStream).read(result -> { ... });
