我想自动化一个消耗大量时间的日常任务。有一个Excel文件包含许多工作簿。每个工作簿都需要保存为单独的CSV文件，以便我能够将其上传到我们的平台。
我创建了以下脚本：

function saveWorksheetsAsCSV() {
  let workbook = ExcelScript.Workbook.getActiveWorkbook();
  let worksheets = workbook.getWorksheets();

  // Get the user's downloads folder path
  let downloadsFolderPath = OfficeExtension.configurableWebSystemService.getDownloadsFolderPath();

  // Get the current date and time
  let currentDate = new Date();
  let formattedDate = currentDate.getFullYear() + "-" + padNumber(currentDate.getMonth() + 1) + "-" + padNumber(currentDate.getDate());
  let formattedTime = padNumber(currentDate.getHours()) + "-" + padNumber(currentDate.getMinutes()) + "-" + padNumber(currentDate.getSeconds());

  worksheets.forEach(function (worksheet) {
    // Create a unique filename based on the worksheet name, date, and time
    let filename = "DiscountPrograms_" + worksheet.getName() + "_" + formattedDate + "_" + formattedTime + ".csv";
    let filePath = downloadsFolderPath + "\\" + filename;

    // Save the worksheet as CSV with semicolon delimiter
    worksheet.saveAs(filePath, ExcelScript.SaveAsFileType.CommaSeparatedValue, { delimiter: ";" });
  });
}

function padNumber(number) {
  return number.toString().padStart(2, '0');
}

字符串
然而，当我运行它时，我只得到这些错误：

[13, 32] Parameter 'worksheet' implicitly has an 'any' type, but a better type may be inferred from usage.
[23, 20] Parameter 'number' implicitly has an 'any' type, but a better type may be inferred from usage.

你能帮我修改一下吗？这是我第一次创作剧本。谢谢！
