| I have an existing workbook that acts as template. I tried to update a cell value in an existing row, meaning the adjacent cell has a value. The problem is that after the file is created and I open it, I get the following error: "Excel found unreadable content in...." I assume the reason is SXSSFWorkbook only handles writing and if a row exists it cant update the contents of the row, which would entail reading and then writing - is this correct or am I experiencing a bug? |
In case anyone else has this problem, check to make sure the length of your SheetName is not too long. I was getting this error when setting the workbook sheet name longer than around 30 characters.
XSSFWorkbook wb = new XSSFWorkbook();
XSSFSheet sheet = wb.createSheet();
wb.setSheetName(0, "Supporting Documentation"); // make sure this is not too long
XSSFWorkbook wb = new XSSFWorkbook();
XSSFSheet sheet = wb.createSheet();
wb.setSheetName(0, "Supporting Documentation"); // make sure this is not too long
