Google Script: Issue deleting Specific Sheet in google spreadsheet - google-apps-script

Question

Situation:
I have a spreadsheet with 20 sheet.
I have other script that copy sheets from other spreadsheet every days to this spreadsheet-
I need to delete every days some specific sheet from a particular spreadsheet.
Problem:
When the script ends to clear the sheets, the spreadsheet hangs and I have to exit and re-enter to the spreadsheet.
I'll appreciate if anyone can help to tunning this script to work without hangging the spreadsheet.
Script:
function shellDeleteSheets(){
var sheets = ['Sheet1','Sheet2','Sheet3','Sheet4','Sheet5'];
for (var s in sheets){
deleteSheetName(sheets[s]);
}
}
function deleteSheetName(stname) {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sh = ss.getSheetByName(stname);
if(!sh) {
return;
}
ss.setActiveSheet(sh);
ss.deleteActiveSheet();
Utilities.sleep(400);
SpreadsheetApp.flush();
}

Answer 1

Try this version I use without issue
function DeleteSheets(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheets = ['sheet1','sheet2','sheet3'];
var numberOfSheets = ss.getSheets().length;
for(var s = numberOfSheets-1; s>0 ; s--){ // in my case I never delete the first sheet
SpreadsheetApp.setActiveSheet(ss.getSheets()[s]);
var shName = SpreadsheetApp.getActiveSheet().getName();
if(sheets.indexOf(shName)>-1){
var delSheet = ss.deleteActiveSheet();
Utilities.sleep(500);
}
}
SpreadsheetApp.setActiveSheet(ss.getSheets()[0]);// send me back to first sheet
}
You could of course use the array of names as an argument for the function or - that's what I do in some cases - give the names of the sheet I need to keep, in this case the if condition is just different .
the sleep can be 400 mS, not sure it makes any difference, I use 500 because at some time I found it more reliable... and I (try to) never change a working solution ;-)
EDIT following your comment :
to make active the sheet called 'Updated' just change the last line of the code like this :
SpreadsheetApp.setActiveSheet(ss.getSheetByName('Updated'));
please note also that I moved this line in the original code, outside of the loop, sorry for this small error ^^
