Google Sheets – Default Number of Rows for ‘Add More Rows’

Edit: fixed version of this: How to automatically insert a new row and retain functions/formulas from last row?

Also copies data validation rules.

Code

// global 
var ss = SpreadsheetApp.getActive();

function onOpen() {
  var menu = [{name:"Add New Last Row", functionName:"addRow"}];
  ss.addMenu("Extra", menu);
}

function addRow() {
  var sh = ss.getActiveSheet(), lRow = sh.getLastRow(); 
  var lCol = sh.getLastColumn(), range = sh.getRange(lRow,1,1,lCol);
  sh.insertRowsAfter(lRow, 1);
  range.copyTo(sh.getRange(lRow+1, 1, 1, lCol), {contentsOnly:false});
}

This is with the assumption my data starts at row 2 (under my headers)

=arrayformula(if(istext(B2:B)*n(C2:C)*n(E2:E)*istext(F2:F),"Ok",if(len(B2:B)+len(C2:C)+len(D2:D)+len(E2:E)+len(F2:F),"MORE INFO",)))
