This code will work

Create a style with a format of %

and set the value as a number (double) and not with %

setCellValue(double value)

The output will be 50%

CellStyle style = workBook.createCellStyle();
style.setDataFormat(workBook.createDataFormat().getFormat("0%"));
cell.setCellStyle(style);
cell.setCellValue(0.50); // set value as number
