Is it possible to export (using Google Scripts) a single sheet to PDF without hiding sheets? - google-apps-script

Question

I would like to be able to export a single specific sheet from a large workbook without having to hide the unrequired sheets. Is that actually possible with Google Scripts?
At the moment I am looping through a list of products, updating a query for each one and then exporting each result to an individual PDF. Basically creating a product "Printout" page for many products.
The code below works quite nicely but it starts by hiding all sheets other than my Printout page. That would be fine except some of the other sheets are protected and not all users that would be using my export functionality have the right to hide sheets.
I've considered adding an unprotect/protect function to my macro but it would be good to know if exporting a single sheet was an option before i went down this route?
The hiding sheets trick was from this post Export Single Sheet to PDF in Apps Script
function exportLoopedSheet(firstRow, lastRow) {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheetName = 'Printout'; // update for print sheet name
var productSheetName = 'ProductList'; // update for final product list
var folderName = 'productPDFs';
var main = ss.getSheetByName(sheetName);
var sheets = ss.getSheets();
var productList = ss.getSheetByName(productSheetName);
var lastProductRow = lastRow;
var firstProductRow = firstRow;
// Hide all sheets other than the Print Sheet
for (var i = 0; i < sheets.length; i++) {
if (sheets[i].getSheetName() !== sheetName) {
sheets[i].hideSheet();
}
}
for (var prodNo = firstProductRow; prodNo < lastProductRow + 1; prodNo ++) {
var currentProduct = productList.getRange('A'+ prodNo).getValue();
main.getRange('B9').setValue(currentProduct);
// Ensure all changes are updated
SpreadsheetApp.flush();
// call the export sheet function
exportSheet();
}
// Unhide the sheets
for (i = 0; i < sheets.length; i++) {
sheets[i].showSheet();
}
}
function exportSheet() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheetName = 'Printout';
var main = ss.getSheetByName(sheetName);
var sheets = ss.getSheets();
//Hide All Empty Rows in the Print Sheet
var maxRows = main.getMaxRows();
var lastRow = main.getLastRow();
if (maxRows-lastRow != 0){
main.hideRows(lastRow+1, maxRows-lastRow);
}
// Save pdf version
var folder = 'productPDF';
var parentFolder = DriveApp.getFolderById('1234'); //add this line...
var folder, folders = DriveApp.getFoldersByName(folder);
if (folders.hasNext()) {
folder = folders.next();
} else {
folder = parentFolder.createFolder(folder);
}
var name = main.getRange("B8").getValue();
folder.createFile(ss.getBlob().setName(name));
// Unhide the rows again
var fullSheetRange = main.getRange(1,1,main.getMaxRows(), main.getMaxColumns());
main.unhideRow(fullSheetRange);
}
