</dependency>- EasyExcel -> Entry point for Easy Excel.
- ExcelSheet -> Excel worksheet information, records the worksheet name and all column data.

.build();
ExcelWriteBuilder excelWriteBuilder = EasyExcel.write().addSheet(sheet);
// Output as xls
excelWriteBuilder.outputXls("Your output path.");
// Output as xlsx
excelWriteBuilder.outputXlsx("Your output path.");The flush method is called in the example to save the batch of added column data. When dealing with large amounts of data, flushing in batches can help avoid OOM issues.
