Delete duplicate pages of data merge

Hi,

first things first: create a backup of your document before you run this script.

Second: insert in line 3 the index number of the page from where it should start the deleting process. The index number is 1 less than the page number. For example: if you want to start from page number 5 the value of startPage should be 4.

var doc = app.activeDocument;
var startPage = "insert start value"; 
var currentPage = startPage;
while (currentPage < doc.pages.length)
{
     doc.pages[currentPage].remove();
     if (currentPage <= doc.pages.length)
          {
               doc.pages[currentPage].remove();
          } else {exit();}
currentPage = currentPage +2;
}
