To insert the countries with a script rather than as keybordists

insertSheets.js

function myFunction() {
  // Made the countries into an array
  var countries = ["Brazil", "Chile", "Colombia", "Uruguay", "France",
  "Nigeria", "Germany", "Algeria",  "Netherlands", "Mexico", "Costa Rica",
  "Greece", "Argentina", "Switzerland", "Belgium", "United States"];
  
 // grabbing the spreadsheed we're working with and naming it ss
  var ss = SpreadsheetApp.getActiveSpreadsheet();
   
  var SHEET_TEAMS = 'Teams';
  
  var sheetControl = ss.getSheetByName(SHEET_TEAMS);
  

  Logger.log(rangeTeams);
  for(i in countries){

   // cell = ranger.getCell(i+1 , 1);
    // each column in the row is an array element, we just need one here and it's the country
    sheetControl.appendRow([countries[i]]);
    
  }
  
}
