Google Apps脚本：将电子表格另存为ODS以进行本地备份

Question

我可以用一只手。 我的公司广泛使用Google表格，并且当我们失去Internet连接时，我们需要一种访问文件的方法。

我无法在该网站上找到任何示例来通过脚本从Google表格创建xls或ods。

我编写了脚本来创建可从本地Google云端硬盘文件夹访问的csv备份的方法。 与每小时触发器一起使用时，此脚本将创建最近一个小时内修改的任何电子表格的每张工作表的csv文件，将它们放在文件夹中，并将其压缩在文件夹中，专门用于备份。 从那里，我可以将zip移至我们的本地服务器。

function backUpMaker() {
  var backupFolderId = '<Id of Backup Folder>';
  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 lastUpdate = sheet.getLastUpdated();
    var timeHourAgo = new Date();
    timeHourAgo = timeNow - 3600000;
    if(lastUpdate >= timeHourAgo){
      var sheetId = sheet.getId();
      var csv = eachSheet(sheetId,newFolderId); 
    }
  }
  var backupFolder = DocsList.getFolderById(backupFolderId);
  try{
    backupFolder.createFile(Utilities.zip(newFolder.getFiles(), timeNow + '.zip'));
  } catch(err) {
    Logger.log(err);
  }
  newFolder.setTrashed(true);
}

function eachSheet(key,newFolderId) {
  var ss = SpreadsheetApp.openById(key);
  var ssId = ss.getId();
  var ssName = ss.getName();
  var howManySheets = ss.getNumSheets();
  try{
   for (var sheetIndex=0; sheetIndex < howManySheets; sheetIndex++) {   
     var activeSheet = ss.getSheets()[sheetIndex];
     var activeName = activeSheet.getName();
     if(activeName != 'Dropdowns'){     //Skip a hidden sheet used for validation on many of our spreadsheets
      var activeId = activeSheet.getSheetId();
      var time = new Date();
      var fileName = time + " Backup: " + ssName + " " + activeName + ".csv";
      var csv = contentCSV(ssId,activeId);
      var folder = DocsList.getFolderById(newFolderId);  
      folder.createFile(fileName, csv, 'text/plain');
     }
   } 
  } catch(err) {
    Logger.log(err)
  }
}

function contentCSV(key,gid) {
  var file = DocsList.getFileById(key);  
  var response =     UrlFetchApp.fetch("https://spreadsheets.google.com/feeds/download/spreadsheets/Export?key=" + key + 
                "&gid=" + gid + "&exportFormat=csv", oAuth());
  var fileText = response.getContentText();  
  return fileText;
}

function oAuth() {
  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",
  };
  return requestData;
}

我将如何修改以另存为ods而不是csv？ 还是有更好的方法保存备份？ 谢谢您的帮助！

由于@ serge-insas的输入，工作代码如下：

注意：要执行此操作，请输入备份文件夹的ID密钥，然后通过注释掉另一个选择来选择ods或xlsx。 然后，您需要为backUpMaker（）设置定时的每小时触发器。 日志将捕获临时移动文件的错误。 开始：

function backUpMaker() {
  var backupFolderId = '0B5--------------------1ZX1k';
  //var exportFormat = 'ods';
  var exportFormat = 'xlsx';
  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 lastUpdate = sheet.getLastUpdated();
    var timeHourAgo = new Date();
    timeHourAgo = timeNow - 3600000;
    if(lastUpdate >= timeHourAgo){
      try{
      var key = sheet.getId();
      var name = sheet.getName();
      var fileName = timeNow + " Backup: " + name + "." + exportFormat;
      var blob = contentBackup(key,exportFormat);
      var folder = DocsList.getFolderById(newFolderId);  
      folder.createFile(blob).rename(fileName);
      } catch(err){
        Logger.log(err);
      }
    }
  }
  var backupFolder = DocsList.getFolderById(backupFolderId);
  try{
    backupFolder.createFile(Utilities.zip(newFolder.getFiles(), timeNow + '.zip'));
  } catch(err) {
    Logger.log(err);
  }
  newFolder.setTrashed(true);
}

function contentBackup(key,exportFormat) {
  try{
    if(exportFormat == 'xlsx'){
      exportFormat = 'xls';
    }  
    var file = DocsList.getFileById(key);  
    var response =     UrlFetchApp.fetch("https://spreadsheets.google.com/feeds/download/spreadsheets/Export?key=" + key + 
                  "&exportFormat=" + exportFormat, oAuth());
    var fileBlob = response.getBlob();  
    return fileBlob;
    } catch(err) {
    Logger.log(err)
    }
}

function oAuth() {
  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",
  };
  return requestData;
}

您的代码只需很少的更改即可获得ods文件。

2个区别：urlFetch中请求的格式变为“ ods”，并且返回的对象不再是字符串而是Blob。

除此之外，我保留了您编写的所有工作表选择功能，而且看起来也很好。 （您做得不错！）。

以下是我从您的代码中复制并按照说明进行更改的完整代码。 我的测试工作正常。

function backUpMaker() {
  var backupFolderId = '0B3qS--------------TXdlY2M';
  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 lastUpdate = sheet.getLastUpdated();
    var timeHourAgo = new Date();
    timeHourAgo = timeNow - 3600000;
    if(lastUpdate >= timeHourAgo){
      var sheetId = sheet.getId();
      var csv = eachSheet(sheetId,newFolderId); 
    }
  }
  var backupFolder = DocsList.getFolderById(backupFolderId);
  try{
    backupFolder.createFile(Utilities.zip(newFolder.getFiles(), timeNow + '.zip'));
  } catch(err) {
    Logger.log(err);
  }
  newFolder.setTrashed(true);
}

function eachSheet(key,newFolderId) {
  var ss = SpreadsheetApp.openById(key);
  var ssId = ss.getId();
  var ssName = ss.getName();
  var howManySheets = ss.getNumSheets();
  try{
   for (var sheetIndex=0; sheetIndex < howManySheets; sheetIndex++) {   
     var activeSheet = ss.getSheets()[sheetIndex];
     var activeName = activeSheet.getName();
     if(activeName != 'Dropdowns'){     //Skip a hidden sheet used for validation on many of our spreadsheets
      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);
     }
   } 
  } catch(err) {
    Logger.log(err)
  }
}

function contentODS(key,gid) {
  var file = DocsList.getFileById(key);  
  var response =     UrlFetchApp.fetch("https://spreadsheets.google.com/feeds/download/spreadsheets/Export?key=" + key + 
                "&gid=" + gid + "&exportFormat=ods", oAuth());
  var fileBlob = response.getBlob();  
  return fileBlob;
}

function oAuth() {
  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",
  };
  return requestData;
}
