You need to escape these special signs:

eg. if you want to have values one and two,three as two columns in a CSV file enclose the second column in quotes:


To escape double quotes " in the column value encolse it with double quotes and use "" to escape the quotes inside the value. eg if you have a field with abc"def it should be escaped as:


So for your case it could be one liner instead of the whole if statement:

data.append("\"").append(cell.getStringCellValue().replaceAll("\"", "\"\"")).append("\",");
