Google apps script to email google spreadsheet excel version [duplicate]

Answer 1

The latest working version is below. Based on this example, i.e. similar as in previous answer but uses Google Service Account which does not require a human going by link to receive a token. You have to install Oath library from Google, the instructions are pretty clear.

var PRIVATE_KEY = 'xxx'
var CLIENT_EMAIL = 'xxx';
var USER_EMAIL=Session.getActiveUser().getEmail()

function getOathService() {
  return OAuth2.createService('GoogleDrive:' + USER_EMAIL)
      // Set the endpoint URL.
      .setTokenUrl('https://accounts.google.com/o/oauth2/token')

      // Set the private key and issuer.
      .setPrivateKey(PRIVATE_KEY)
      .setIssuer(CLIENT_EMAIL)

      // Set the name of the user to impersonate. This will only work for
      // Google Apps for Work/EDU accounts whose admin has setup domain-wide
      // delegation:
      // https://developers.google.com/identity/protocols/OAuth2ServiceAccount#delegatingauthority
      .setSubject(USER_EMAIL)

      // Set the property store where authorized tokens should be persisted.
      .setPropertyStore(PropertiesService.getScriptProperties())

      // Set the scope. This must match one of the scopes configured during the
      // setup of domain-wide delegation.
      .setScope('https://www.googleapis.com/auth/drive');
}


function sendEmail() { 
  var oathService = getOathService();
  var ssID = SpreadsheetApp.getActiveSpreadsheet().getId(); 
  var file = Drive.Files.get(ssID );
  var url = file.exportLinks[MimeType.MICROSOFT_EXCEL];

  var file = UrlFetchApp.fetch(url, {
    headers: {
      Authorization: 'Bearer ' + oathService.getAccessToken()
    }
  });
   var attachments = [{
    fileName:'xxx.xls',//TODO DATE
    content: file.getBlob().getBytes(), 
    mimeType:"application//xls",
    headers: {
      Authorization: 'Bearer ' + oathService.getAccessToken()
    }
  }];

  MailApp.sendEmail('email@domain.com', 'xxx', 'Hi,\n\nPlease see the last data in attachment',{attachments:attachments});
}
