使用 GAS 将 google 电子表格转换为 XLSX 或 ODS

我想将一些谷歌电子表格转换为Excel（首选xlsx）。
我已经阅读了几个有关如何实现此目标的线程，但我无法运行它。
我读过的主题包括Google Apps 脚本：将电子表格保存为 ODS 以进行本地备份 and Google Apps 脚本通过电子邮件发送 Google 电子表格 Excel 版本

为了接近我发现的代码并获取有关其不起作用的更多信息，我修改了我发现的代码，使其仅处理几个文件，并且 try-catch 也已被删除。

function contentODS(key, gid) 
{
   var file = DocsList.getFileById(key); 

   var fetchParameters = oAuth();

   var url = "https://spreadsheets.google.com/feeds/download/spreadsheets/Export?key=" + key + "&gid=" + gid + "&exportFormat=ods";
   var response = UrlFetchApp.fetch(url, fetchParameters);

   var fileBlob = response.getBlob();  
   return fileBlob;
}

function oAuth()

  var oauthConfig = UrlFetchApp.addOAuthService("spreadsheets");

  var folders = DriveApp.getRootFolder().getFoldersByName(backupDirectory);
  var backupFolderId = undefined;
  if (folders.hasNext()) backupFolderId = folders.next().getId();
  else return;  // File doe not exist

  var timeNow = new Date();  
  var newFolder = DocsList.createFolder(timeNow);
  var newFolderId = newFolder.getId();
  newFolder.addToFolder(DocsList.getFolderById(backupFolderId));
  newFolder.removeFromFolder(DocsList.getRootFolder());
  var sheets = DriveApp.getFilesByType(MimeType.GOOGLE_SHEETS);

    var sheet = sheets.next();
    var name = sheet.getName();

    var filesToSave = [ 'My-Agenda', 'My-Kalender' ];
    var numFiles = filesToSave.length;

    for (var i=0; i<numFiles; i++)
    {
       if (name == filesToSave[i])
       {
          var sheetId = sheet.getId();
          var csv = eachSheet(sheetId, newFolderId);

  var backupFolder = DocsList.getFolderById(backupFolderId);
  var newFiles = newFolder.getFiles();
  var numFiles = newFiles.length;

  if (numFiles > 0)
  {
     var nameZipFile = timeNow + '.zip';
     backupFolder.createFile(Utilities.zip(newFiles, nameZipFile));
  } 

  newFolder.setTrashed(true);
}

运行 backupmaker 失败var response = UrlFetchApp.fetch(url, fetchParameters);
并指示服务电子表格验证失败

我应该做什么才能让它发挥作用。

您可以使用高级驾驶服务获取导出 URL 并使用脚本的 OAuth2 令牌下载文件。

function exportAsExcel(spreadsheetId) {
  var file = Drive.Files.get(spreadsheetId);
  var url = file.exportLinks['application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'];
  var token = ScriptApp.getOAuthToken();
  var response = UrlFetchApp.fetch(url, {
    headers: {
      'Authorization': 'Bearer ' +  token
    }
  });
  return response.getBlob();
}

function test() {
  var spreadsheetId = 'SPREADSHEET ID HERE';
  DriveApp.createFile(exportAsExcel(spreadsheetId));
}
