I have an application made on google than handdle different sheets on a google workbook. I need to add a button to allow users download some of these sheets but in an excel format if is possible. I took one code from StackOv and try to modify it, as i don´t want it name the file and save it in drive, i only need it download as same that when from excel it is download in Book1 ("libro1") without saving anywhere. THK!
var ss = SpreadsheetApp.openById("fffffffffffffffffffffffffffff...myID");
var sheetId = ss.ss.getSheetByName('nameSheetNeedToDownload');
var url = "https://docs.google.com/spreadsheets/d/" + sheetId + "/export?format=xlsx&access_token=" + ScriptApp.getOAuthToken();
var blob = UrlFetchApp.fetch(url).getBlob().setName(name + ".xlsx");
createFile(blob); // here need to create but without saving
