Copy Name from one sheet to another

Question

I have two separate sheets, let's call them Data and Duplicate. They both have their own set of tabs. Each tab has its own set of data. I want the name of the sheet "Data" to rename the first tab in Duplicate sheet tab1.

How can this be done using app script?

Answer 1

Put this in spreadsheet Data

function renamefirst() {
  const ss = SpreadsheetApp.openById("id of spreadsheet Duplicate");
  const sh = ss.getSheets()[0];
  sh.setName("Tab1")
}
