Google app scripts: email a spreadsheet as excel
(2 answers)
Closed 2 years ago.
I would like to write an apps script to email an excel version of my Google Spreadsheet. I know I can save the spreadsheet as an Excel file. I am not sure if I can use the script to email the excel version out as an attachment. How can this be done?

Answer 1

After an answer on another recent post (Thomas van Latum), I tried the suggested doc api and get an interesting result... here is the test code I used and that is working nicely except the file is in xlsx format, not in xls but this is not necessarily an issue these days :
function googleOAuth_(name,scope) {
var oAuthConfig = UrlFetchApp.addOAuthService(name);
oAuthConfig.setRequestTokenUrl("https://www.google.com/accounts/OAuthGetRequestToken?scope="+scope);
oAuthConfig.setAuthorizationUrl("https://www.google.com/accounts/OAuthAuthorizeToken");
oAuthConfig.setAccessTokenUrl("https://www.google.com/accounts/OAuthGetAccessToken");
oAuthConfig.setConsumerKey('anonymous');
oAuthConfig.setConsumerSecret('anonymous');
return {oAuthServiceName:name, oAuthUseToken:"always"};
}
function test(){
var id = 'spreadsheet_ID'
var url = 'https://docs.google.com/feeds/';
var doc = UrlFetchApp.fetch(url+'download/spreadsheets/Export?key='+id+'&exportFormat=xls',
googleOAuth_('docs',url)).getBlob()
DocsList.createFile(doc).rename('newfile.xls')
}
note : if you don't rename it, its default name is Export.xlsx , it might be more usefull to get its ID to use it later...
so the last line could be like this instead :
var xlsfileID = DocsList.createFile(doc).getId()
EDIT : to trigger the authorization process, try a small function like this, run it from the script editor
function autorise(){
// function to call to authorize googleOauth
var id=SpreadsheetApp.getActiveSpreadsheet().getId();
var url = 'https://docs.google.com/feeds/';
var doc = UrlFetchApp.fetch(url+'download/documents/Export?exportFormat=html&format=html&id='+id,
googleOAuth_('docs',url)).getContentText();
}

Answer 2

As I spent about four hours of playing Rumpelstiltskin because none of the typically very old code snippets for the old Spreadsheet versions and the old OAUTH you can find when googling "google docs script send excel attachment" or similar (i.e. you want to take an existing Spreadsheet, convert it to Excel format and send it as email attachment) actually worked, I finally found the solution.
To create the actual attachment content, neither the supposed res.getContent() nor res.getBlob() nor res.getBytes alone worked. These hints are misleading!
The only thing that works for me is response.getBlob().getContent()!
Whole code :
function sendCurrentDocAsEmail() {
var driveService = getDriveService();
var ssID = SpreadsheetApp.getActiveSpreadsheet().getId();
var sheetName = SpreadsheetApp.getActiveSpreadsheet().getName();
var email = "recipient#demo.com"
var subject = "Here be Subjects";
var body = "Don't even think about learning how to code. It's wasted time.";
var file = Drive.Files.get(ssID );
var url = file.exportLinks[MimeType.MICROSOFT_EXCEL];
var response = UrlFetchApp.fetch(url, {
headers: {
Authorization: 'Bearer ' + driveService.getAccessToken()
}
});
var attachments = [{
fileName:sheetName+".xlsx",
content: response.getBlob().getBytes(), // this single line has cost me hours!
mimeType:"application//xls",
headers: {
Authorization: 'Bearer ' + driveService.getAccessToken()
}
}];
MailApp.sendEmail(email,subject ,body, {attachments:attachments});
}
Where getDriveService() is a function from Google's "OAuth2 for Apps Script" readme on https://github.com/googlesamples/apps-script-oauth2

Answer 3

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});
}

Answer 4

The one that worked for me:
var AUTH_TOKEN = "Enter your OAuth_Token";
ssID = SpreadsheetApp.getActiveSpreadsheet().getId();
var url = "http://spreadsheets.google.com/feeds/download/spreadsheets/Export?key="+ ssID + "&exportFormat=xls";
//Add &gid=x at the end of above url if you only want a particular sheet
var auth = "AuthSub token=\"" + AUTH_TOKEN + "\"";
var res = UrlFetchApp.fetch(url, {headers: {Authorization: auth}});
var attachments = [{fileName:"<Filename>.xls", content: res.getContent(),mimeType:"application/vnd.ms-excel"}];
MailApp.sendEmail("<recipient's email id>", "<email subject>", "<email body>", {attachments: attachments});
Get OAuth documentation & you token from here https://developers.google.com/accounts/docs/OAuth2

Answer 5

Use the following snippet of code after modifying it to suit your needs
var file = DocsList.getFileById(FILE_ID);
var attachment = file.getAs('application/vnd.ms-excel');
MailApp.sendEmail("abcd#example.com", "Subject", " Body" , {"fileName": "Your_file_name" , "mimeType" : "application/vnd.ms-excel" , "content":attachment.getBytes() } );
Note that this code is not tested, so please feel free to fix an error or two that might pop up
