apache poi - Export to excel while it contains huge data

Question

While I am exporting excel which has huge data(ex:100 rows) I am getting below alert while opening sheet. And if we click on proceed,it is opening in protected view.

While we save this excel it is alerting as "unable to save in protected view" and if we proceed the styles and font settings are altered in the excel sheet saved.

What can I do to avoid this?

Answer 1

  //u can call this style method before loops where we are creating cells
   HSSFCellStyle yellowStyle = getYellowColoreBasedOnNewField(workBook);     

  private HSSFCellStyle getYellowColoreBasedOnNewField(HSSFWorkbook workBook) {
    HSSFCellStyle style = workBook.createCellStyle();
    HSSFFont font = createAndSetFontStyle(workBook);
    setYellowColor(style, font);
    return style;
} 

    private HSSFFont createAndSetFontStyle(HSSFWorkbook wb) {
    HSSFFont font = wb.createFont();
    font.setFontName(XSSFFont.DEFAULT_FONT_NAME);
    font.setFontHeightInPoints((short)10);
    return font;
}
