Question

How do I set the last sheet in my spreadsheet to the active sheet? This code isn’t working. Not sure what I’m doing wrong…

    var logbook = SpreadsheetApp.openById("my key code");

    var totalSheets = logbook.getNumSheets();
    var lastSheet = logbook.getSheets[totalSheets];
    var currentSheet = logbook.setActiveSheet(lastSheet);

I’m getting an error:

Can not find method setActiveSheet

Answer 1

Try it like this instead :

var logbook = SpreadsheetApp.openById("my key code");
var totalSheets = logbook.getNumSheets();
var lastSheet = logbook.getSheets()[totalSheets-1];// !! () and -1 because if 3 sheets, last sheet is [2]
var lastSheetName = lastSheet.getName();
var currentSheet = SpreadsheetApp.setActiveSheet(lastSheet);

that said, it seems complicated to access a single sheet… what I do usually is simply that :

var ss = SpreadsheetApp.openById(key);// ss for spreadsheet
var sh = ss.getSheetByName('Sheet1');// sh for sheet

that’s pretty standard in a lot of example code…
