Downloading a PDF version of the open spreadsheet in Google Drive via scripts - google-apps-script

Question

I've been reading up on how to save a spreadsheet to PDF via Google Docs Scripting. Most suggestions I've come across reference using something like:
theOutputFile.saveAndClose();
DocsList.createFile(theOutputFile.getAs('application/pdf')).rename(theOutputName+".pdf");
That is, they reference the saveAndClose() function. I don't want to save or close my spreadsheet - but I do want to download the current sheet as a PDF.
Any suggestions? Thanks.

Answer 1

For saving the current sheet as a PDF, you can hide all the other sheets, save the current, & then show all sheets again.
The pdf creation might start before the end of the sheets' hiding and then will include 2 sheets - the current & the last sheets - in the pdf file.
Adding a sleep or a confirmation msgbox, between showOneSheet & createPdf eliminated the problem.
This answer is a variation of Marco Zoqui's answer: "To send a single sheet you may hide all other before sending" in Google Apps Script to Email Active Spreadsheet
var sheet = SpreadsheetApp.getActiveSheet();
var sheetToSave = sheet.getName();
showOneSheet(sheetToSave);
Utilities.sleep(2000);
createPdf("TestFolder", "TestPDF");
showAllSheets();
function showOneSheet(SheetToShow) {
var sheets = SpreadsheetApp.getActiveSpreadsheet().getSheets();
for(var i in sheets){
if (sheets[i].getName()==SheetToShow){
sheets[i].showSheet();
}
else {
sheets[i].hideSheet();
}
}
}
function showAllSheets() {
var sheets = SpreadsheetApp.getActiveSpreadsheet().getSheets();
for(var i in sheets){
sheets[i].showSheet();
}
}
function createPdf(saveToFolder, fileName){
var ssa = SpreadsheetApp.getActiveSpreadsheet();
var pdf = ssa.getAs("application/pdf");
try {
var folder = DocsList.getFolder(saveToFolder);
}
//Create Folder if not exists
catch(error){
folder = DocsList.createFolder(saveToFolder);
}
var file = folder.createFile(pdf);
file.rename(fileName);
return file;
}

Answer 2

I was able to get it to work using #hsgv's answer, however, this is the version I ended up using based on this.
// global save to folder variable:
var folderName = "My/Special/Folder";
function createInvoiceInGoogleDrive(){
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var sheet = spreadsheet.getActiveSheet();
// getting some values from the spreadhseet for the file name
var invoiceNumber = sheet.getRange("E3").getValue();
var vendor = sheet.getRange("A9").getValue();
var fileName = invoiceNumber + ' - ' + vendor + " - Invoice.pdf";
var pdfBlob = sheetToPDF(spreadsheet, sheet);
pdfBlob.setName(fileName);
var folder = getOrCreateFolder(folderName);
var matchingFileList = folder.find(fileName);
if ( matchingFileList.length > 0 ) {
Browser.msgBox("ERROR: New invoice not created. " + fileName + " already exists at " + folderName);
return false;
} else {
var f = folder.createFile(pdfBlob);
spreadsheet.toast('Created a new invoice on Google Drive!');
return true;
}
}

function sheetToPDF(spreadsheet, sheet) {
var ssID = spreadsheet.getId();
var gid = sheet.getSheetId();
// &gid=x at the end of above url if you only want a particular sheet
var url2 = "http://spreadsheets.google.com/feeds/download/spreadsheets/Export?key=" + ssID +
"&gid=" + gid +
"&fmcmd=12&size=7&fzr=true&portrait=true&fitw=true&locale=en&gridlines=false&printtitle=false&sheetnames=false&pagenum=UNDEFINED&attachment=true";
// AUTH TOKEN required to access the UrlFetchApp call below. You can receive it

var AUTH_TOKEN = "{GET YOUR OWN AUTH TOKEN}";
var auth = "AuthSub token=\"" + AUTH_TOKEN + "\"";
var res = UrlFetchApp.fetch(url2, {headers: {Authorization: auth}}).getBlob();
return res;
}
/**

function getOrCreateFolder(folderName) {
try {
var theFolder = DocsList.getFolder(folderName);
} catch(error){
var theFolder = DocsList.createFolder(folderName);
}
return theFolder;
