Below code will convert and download JSON array to csv as a file.

 function exportJSONToCSV(objArray) {
    var arr = typeof objArray !== 'object' ? JSON.parse(objArray) : objArray;
    var str =
      `${Object.keys(arr[0])
        .map((value) => `"${value}"`)
        .join(',')}` + '\r\n';
    var csvContent = arr.reduce((st, next) => {
      st +=
        `${Object.values(next)
          .map((value) => `"${value}"`)
          .join(',')}` + '\r\n';
      return st;
    }, str);
    var element = document.createElement('a');
    element.href = 'data:text/csv;charset=utf-8,' + encodeURI(csvContent);
    element.target = '_blank';
    element.download = 'export.csv';
    element.click();
  }
