Question

I want to convert a PDF file into a CSV file.
I am using iText library for this.
The program is working fine but the output is not in desired format.
All the data is coming in first line of the csv file. The output should be exactly same as pdf file(means with line breaks).
Please help.
Thanks in advance.

Document document = new Document();
  document.open();
  PdfReader reader = new PdfReader("C:\\Indiaops-projects\\PREMIUM_PAID_ACKNOWLEDGEMENT.pdf");
  PdfDictionary dictionary = reader.getPageN(1);
  AcroFields fileds = reader.getAcroFields();
  PRIndirectReference reference = (PRIndirectReference) 
            dictionary.get(PdfName.CONTENTS);
                    PRStream stream = (PRStream) PdfReader.getPdfObject(reference);
                    byte[] bytes = PdfReader.getStreamBytes(stream);
                    PRTokeniser tokenizer = new PRTokeniser(bytes);
                    FileOutputStream fos=new FileOutputStream("C:\\Indiaops-projects\\pdf.csv");
                    StringBuffer buffer = new StringBuffer();
                    StringBuffer data = new StringBuffer();
                    int i=0;
                    while (tokenizer.nextToken()) {
                    if (tokenizer.getTokenType() == PRTokeniser.TK_STRING) {
                        String value = tokenizer.getStringValue();

                        if("x-none".equals(value)){
                            String datastr =data.toString();
                            if(!"".equals(datastr)){
                                buffer.append("\""+datastr+"\",");
                                data = new  StringBuffer();
                            }
                        }else{
                               data.append(value);
                        }
                     }
                  }
            String test=buffer.toString();
            StringReader stReader = new StringReader(test);
            int t;
            while((t=stReader.read())>0)
            fos.write(t);
            document.add(new Paragraph(".."));
            document.close();

You need to introduce a line break ‘\n’ in the buffer after each table row.

buffer.append("\n");
