Data not showing in the oracle Sql Database importing from .CSV

Question

I scraped a website and fetch the data into the .CSV file. This process has been successfully executed and working properly. But, when I tried to fetch the data in the table of Oracle Sql Database it only brings the first row of the .CSV file and don't retrieve the other lines of the data. I am trying to retrieve the data of CSV file through SQLLoader written in create script. When I call any other CSV through that script it is working fine and brings all the data. But, this matter only comes in the file which has been created through the java program.
Java code is as follows.

public static void parsingHTML() throws Exception {
  for (int i = 1; i <= 1; i++) {

    tbodyElements = doc.getElementsByTag("tbody");

    if (tbodyElements.isEmpty()) {
        throw new Exception("Table is not found");
    }
    elements = tbodyElements.get(0).getElementsByTag("tr");

    for (Element trElement : elements) {
        trElement2 = trElement.getElementsByTag("tr");
        tdElements = trElement.getElementsByTag("td");
        File fold = new File("C:\\convertedCSV9.csv");
        fold.delete();
        File fnew = new File("C:\\convertedCSV9.csv");
        FileWriter sb = new FileWriter(fnew, true);

        for (Iterator<Element> it = tdElements.iterator(); it.hasNext();) {

            Element tdElement1 = it.next();
            final String content2 = tdElement1.text();
            if (it.hasNext()) {
                sb.append("\n");

            }
            for (Iterator<Element> it2 = trElement2.iterator(); it.hasNext();) {
                Element tdElement2 = it.next();
                final String content = tdElement2.text();

                if (it2.hasNext()) {

                    sb.append(formatData(content));
                    sb.append("   ,   ");

                }
                if (!it.hasNext()) {
                    String content1 = content.replaceAll(",$", " ");
                    sb.append(formatData(content1));
                    it2.next();

                }

            }

            System.out.println(sb.toString());
            sb.flush();
            sb.close();

        }
        System.out.println(sampleList.add(tdElements));

    }
  }
}

And Create Script is

create table TEST_EXCEL_OPEN_END_SMRY
(
  fund_name     VARCHAR2(150),
  rating        VARCHAR2(50),
  validity_date VARCHAR2(50),

  days_90       VARCHAR2(50),
  days_180      VARCHAR2(50),
  days_270      VARCHAR2(50),
  days_365      VARCHAR2(50)
)
organization external

        FIELDS TERMINATED BY ','
        MISSING FIELD VALUES ARE NULL
        (

    DAYS_30 ,

    DAYS_180,
    DAYS_270,
    DAYS_365
        )
  )
  location (DIR_KSE:'convertedCSV9.csv')
)
reject limit UNLIMITED;

PS: Path of the DIR_KSE is correct. I am also attaching the snapshot of CSV and Database result.

Your Java code is using a line feed character (LF) as a line separator:

            sb.append("\n");

That's fine in the Linux/UNIX world, but it seems your Oracle instance is running on Windows, and by default that expects Windows-style line separators, with both carriage return and line feed (CRLF).

When it reads the file it sees the LF on its own as just a character in the line, so it essentially sees the entire file as a single line, as J.Chomel suggested earlier.

You can either convert the line endings with a utility, or generate the file with the expected Windows separators by changing your code to:

            sb.append("\r\n");
