CSV file generation from HTML inputted data

I was trying to pass user inputted data in HTML form to csv file on local drive. But seems some error in it.

I have tried below code even that is copied from other sources.

    <html>
  <head>
  <script language="javascript">
    function WriteToFile(passForm) {
      var fso = new ActiveXObject("Scripting.FileSystemObject");
      var fileLoc = "C:\\sample.txt";
      var file = OpenTextFile(fileLoc,2,true,0);
     file.write("File handling in Javascript");
      file.Close();
      alert('File created successfully at location: ' + fileLoc);
     }
  </script>
  </head>
  <body>
  <p>create a csv file with following details -</p>
  <form>
    Type your first name: <input type="text" name="FirstName" size="20"><br>
    Type your last name: <input type="text" name="LastName" size="20"><br>
    <input type="button" value="submit" onclick="WriteToFile(this.form)">
  </form>
  </body>
</html>
</br></br></html>

CSV file is not getting created and cant get any error in HTML.

You were not using the variable fso to call OpenTextFile, you should also keep in mind that IE has permissions to write in the path

This should work for you:

<html>
<head>
    <script language="javascript">
        function WriteToFile(passForm) {
            var fso = new ActiveXObject("Scripting.FileSystemObject");
            var fileLoc = "C:\\Users\\yourUser\\sample.csv";
            var file = fso.OpenTextFile(fileLoc,2,true,0);
            file.write("File handling in Javascript");
            file.Close();
            alert('File created successfully at location: ' + fileLoc);
        }
    </script>
</head>
<body>
    <p>create a csv file with following details -</p>
    <form>
        Type your first name: <input type="text" name="FirstName" size="20"><br>
        Type your last name: <input type="text" name="LastName" size="20"><br>
        <input type="button" value="submit" onclick="WriteToFile(this.form)">
    </form>
</body>
</html>

You can also use this solution that works for several browsers:

<html>
<head>
    <script language="javascript">
        function downloadCSV(form) {
            const content = 'Write your csv content here!!';
            const mimeType = 'text/csv;encoding:utf-8';
            const fileName = 'download.csv';
            const a = document.createElement('a');

            if (navigator.msSaveBlob) { // IE10
                navigator.msSaveBlob(new Blob([content], {
                    type: mimeType
                }), fileName);
            } else if (URL && 'download' in a) { //html5 A[download]
                a.href = URL.createObjectURL(new Blob([content], {
                    type: mimeType
                }));
                a.setAttribute('download', fileName);
                document.body.appendChild(a);
                a.click();
                document.body.removeChild(a);
            } else {
                location.href = 'data:application/octet-stream,' + encodeURIComponent(content); // only this mime type is supported
            }
        }
    </script>
</head>
<body>
    <p>create a csv file with following details -</p>
    <form>
        Type your first name: <input type="text" name="FirstName" size="20"><br>
        Type your last name: <input type="text" name="LastName" size="20"><br>
        <input type="button" value="submit" onclick="downloadCSV(this.form)">
    </form>
</body>
</html>
