JFlat's purpose is to convert flat files to Java Beans and vice versa. Some supported formats are CSV, fixed-width, arbitrary delimiters, and excel files. There are also tools to generate Java Beans to/from JDBC and Swing tables. JFlat is highly extensible and can be adopted to support additional formats.
