• Universal Excel import and export tools.
• Support is derived from the List<Map>.
• Support from the List<POJO> import and export.
• Support from inside the List<POJO and List<POJO> inside> import and export.
• To support the export of similar curriculum structure type cross table.
• Support for Internationalization.
• Don't write a configuration file.
• Use the adapter pattern, data import and export support arbitrary types, users can also write your own adapter custom data types!
