Get specific Range to Export - google-apps-script

Question

can anyone help me with my problem?
Need to export a specific range (A1:J39), not the full sheet.
function SavePDFtoDrive() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var ltrsht = ss.getSheetByName("Schichtübergabe-Protokoll");
var datasheet = ss.getSheetByName("Daten");
var sheets=SpreadsheetApp.getActiveSpreadsheet().getSheets();
for(var i =0;i<sheets.length;i++){
if(sheets[i].getName()!="Schichtübergabe-Protokoll"){ sheets[i].hideSheet() }
}
var pdf = DriveApp.getFileById(ss.getId());
var theBlob = pdf.getBlob().getAs('application/pdf').setName(datasheet.getRange("I8").getValue()+".pdf");
var folderID = "1dyKFNvQWrSiNFA8N5PyUMPJQpWSVhsLf"; // Folder id to save in a folder
var folder = DriveApp.getFolderById(folderID);
var newFile = folder.createFile(theBlob);
}

Answer:
Rather than getting your blob using DriveApp, you can obtain your blob from an export URL using UrlFetchApp.
More Information:
When you use DriveApp to create a blob of a file, it doesn't have the functionality to read the specifics of the file. In this case, you can't specify the range of a Sheet you wish to export with DriveApp.
You can, however, build a URL with all your export parameters and create your export in Drive by creating a blob of the response and creating it in Drive.
Code:
function SavePDFtoDrive() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var ltrsht = ss.getSheetByName("Schichtübergabe-Protokoll");
var datasheet = ss.getSheetByName("Daten");
// build your URL:
var url = "https://docs.google.com/spreadsheets/d/" + ss.getId() + "/export?"
//define your parameters:
var params = 'exportFormat=pdf&format=pdf'
+ '&portrait=false'
+ '&fitw=true'
+ '&gid=' + ltrsht.getSheetId()
+ '&range=A1:J39';
//get token for UrlFetch:
var token = ScriptApp.getOAuthToken();
var response = UrlFetchApp.fetch(url + params, {
'headers': {
'Authorization': 'Bearer ' + token
}
});
var fileName = datasheet.getRange("I8").getValue() + ".pdf";
var theBlob = response.getBlob().setName(fileName);
var folderID = "1Hp-P1dzWaKHhhS2FTPzKib6pwJibS12t";
var folder = DriveApp.getFolderById(folderID);
folder.createFile(theBlob);
}
