Please set fill type as none as operation in MS Excel.
See following codes:

Workbook workbook = new Workbook();
ShapeCollection shapes = workbook.getWorksheets().get(0).getShapes();
TextBox s = shapes.addTextBox(0,0,0,0,100,200);
s.setText("Hello");
s.getLine().setFillType(FillType.NONE);
workbook.save(dir +"dest.xlsx");
