Deleting specific data from multiple Google Sheets - google-apps-script

Question

I am trying to clear data from multiple sheets. I have a code that works for the current active sheet and data ranges I need, but I can not for the life of me figure out how to make it clear the same data from multiple sheets. Here is the code:
// This section adds the top menu
function onOpen() {
SpreadsheetApp.getUi().createMenu('Reset')
.addItem("Formulas Only", "ResetFormulas")
.addItem("Entire Page", "ResetPage")
.addToUi()
}
// This section makes a button to reset the whole page copies the entire page
function ResetPage() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName('Data1'); // Enter tab name of what you’re copying from
sheet.getRange('A1:U39').copyTo(ss.getRange('A1:U39')) //enter entire tab range
}
// This section copies only the cells you specify
function ResetFormulas() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName('Sheet12'); // Enter tab name here of what you’re copying
from
//Header
sheet.getRange('B6:E20').copyTo(ss.getRange('B6:E20')) //first range you’re copying
sheet.getRange('N6:Q20').copyTo(ss.getRange('N6:Q20')) //next range
sheet.getRange('B25:E39').copyTo(ss.getRange('B25:E39')) //etc
sheet.getRange('N25:Q39').copyTo(ss.getRange('N25:Q39')) //you get it
}
What specifically would I change to make it clear multiple sheets rather than the active one?

Answer 1

The line sheet.getRange('A1:U39').copyTo(ss.getRange('A1:U39')) specifies that data shall be copied to the range 'A1:U39' in the active spreadsheet
It doe not specify in which sheet the range is located, this is why Apps Script assumes that you want to copy into the active sheet
If you want to chose instead a different sheet - you need to specify the sheet
Sample:
function ResetPage() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName('Data1'); // Enter tab name of what you’re copying from
var sheet2 = ss.getSheetByName('Data2'); // Enter tab name of what you’re copying from
sheet.getRange('A1:U39').copyTo(sheet2.getRange('A1:U39')) //enter entire tab range
}
