Tweak your report generator and try the following tricks before
passing strings to SXSSFCell:
(a) string.replaceAll("\\s+", ""); // replace multiple white spaces
with a single space
(b) string.replace(' ', '_'); // replace white spaces with underscore
Does any of (a) and (b) help?
My hunch is that the problem is in something else, not in double white
spaces. At least, I can't reproduce the problem with the following
code snippet:
Workbook wb = new SXSSFWorkbook();
Sheet sh = wb.createSheet();
for(int i = 0; i < 10000; i++) {
Row row = sh.createRow(i);
row.createCell(0).setCellValue("ALEXANDRE__MARINHO DE SOUZA");
row.createCell(1).setCellValue("ALEXANDRE MARINHO DE SOUZA");
row.createCell(2).setCellValue("ALEXANDRE MARINHO DE SOUZA");
row.createCell(3).setCellValue("ALEXANDRE MARINHO DE SOUZA");
}
FileOutputStream out = new FileOutputStream("/temp/test.xlsx");
wb.write(out);
out.close();
The generated file is readable and all spaces are there.
