• I am trying to read the content of a csv file by taking an input in an Microsoft Office Excel add-in.
• Facing the error as taskpane.js:84 TypeError: Failed to execute 'readAsText' on 'FileReader': parameter 1 is not of type 'Blob'.
• HTML

<form>
<input type="file" id="csv-file">
<button type="submit" id="csv-data">Submit</button>
</form>

• JS

async function import_from_csv() {
  try {
    var file = document.getElementById("csv-file");
    var files = file[0];
    var reader = new FileReader();
    reader.readAsText(files);
    reader.onload = function (event) {
      var csv = event.target.result;
      var data = $.csv.toArrays(csv);
      console.log("Data =", data);
    };
  } catch (error) {
    console.error(error);
  }
}
