Hi Yegor,
I have done all the steps mentioned forum post but I am still getting the
same "unreadable content" Dialog Box. I am using POI-3.8 and have Excel 2007
installed on my machine. My code works fine and xlsx opens without issues if
I write to FileOutputStream as mentioned in one of the posts earlier while
if I write to response.getOutputStream(), I get "unreadable content" dialog
box. Please find my code snippet below, I am not doing anything fancy just
writing 70k lines to xlsx.
My Controller Code
response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
response.setHeader("Content-Disposition","attachment;filename=" + fileName);
service.createPOCDoc(response.getOutputStream());
My Service Code
public void createPOCDoc(OutputStream output) throws IOException{
Workbook wb = new XSSFWorkbook();
createDataSheet(wb.createSheet("data"), 70000);
wb.write(output);
output.flush();
output.close();
}
private void createDataSheet(Sheet sheet, int max_rows) {
for (int i = 0; i < max_rows; i++) {
Row row = sheet.createRow(i);
Cell cell = row.createCell(0);
cell.setCellValue("row number - " + i);
}
System.out.println("added " + max_rows);
}
