使用 GAS 将 google 电子表格转换为 XLSX 或 ODS

Question

我想将一些 Google 电子表格转换为 Excel（首选 xlsx）。
我已经阅读了几个关于如何实现这一点的主题，但我无法让它运行。
我读过的线程中有Google Apps Script: Save Spreadsheet as ODS for Local Backup 和Google apps script to email google spreadsheet excel version

为了与我发现的代码保持接近并获得有关它为什么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 已被删除。

****************** Not working code **************
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()
{ // https://stackoverflow.com/questions/24493203/google-apps-script-save-spreadsheet-as-ods-for-local-backup
  var oauthConfig = UrlFetchApp.addOAuthService("spreadsheets");
  var scope = "https://spreadsheets.google.com/feeds" 
  oauthConfig.setConsumerKey("anonymous");
  oauthConfig.setConsumerSecret("anonymous");
  oauthConfig.setRequestTokenUrl("https://www.google.com/accounts/OAuthGetRequestToken?scope=" + scope);
  oauthConfig.setAuthorizationUrl("https://accounts.google.com/OAuthAuthorizeToken");    
  oauthConfig.setAccessTokenUrl("https://www.google.com/accounts/OAuthGetAccessToken");   

  var requestData =
  {
    "oAuthServiceName":   "spreadsheets",
    "oAuthUseToken":      "always",
    "muteHttpExceptions": true,
    "method":             "DELETE",
  };
  return requestData;
}

function eachSheet(key, newFolderId)
{
  var ss = SpreadsheetApp.openById(key);
  var ssId = ss.getId();
  var ssName = ss.getName();
  var howManySheets = ss.getNumSheets();

  for (var sheetIndex=0; sheetIndex < howManySheets; sheetIndex++)
  {   
     var activeSheet = ss.getSheets()[sheetIndex];
     var activeName = activeSheet.getName();
     var activeId = activeSheet.getSheetId();
     var time = new Date();
     var fileName = time + " Backup: " + ssName + " " + activeName + ".ods";
     var blob = contentODS(ssId, activeId);
     var folder = DocsList.getFolderById(newFolderId);  
     folder.createFile(blob).rename(fileName);
   } 
}

function backUpMaker()
{
  var backupDirectory = 'Backup';
  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);
  while (sheets.hasNext())
  {
    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); 
          break;
       }  
    }   
  }
  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);
}

在 var response = UrlFetchApp.fetch(url, fetchParameters); 处运行 backupmaker 失败
并表示服务电子表格的验证失败

我应该怎么做才能让它工作。

您可以使用Advanced Drive Service 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));
}
