Indesign script for merging documents in one document

@Mr1857 

I'm not JS guy so this is a very "crude" solution:

var a=0;

var CheckIfEven = true;
var RemoveSections = true;

for (a=app.documents.length-1;a>0;a--)
{
   if (!CheckIfEven || (app.documents[a].pages.length % 2 === 0 && app.documents[0].pages.length % 2 === 0)) 
   {
      // do nothing
   } 
   else 
   {
      app.documents[0].pages.add();
   };
   app.documents[a].pages.itemByRange(0,-1).duplicate(LocationOptions.AFTER, app.documents[0].pages[-1]);
   app.documents[a].close(SaveOptions.NO);
};

if (RemoveSections)
{
   for (a=app.activeDocument.sections.length-1;a>0;a--)
   {
      app.activeDocument.sections[a].remove();
    };
}

You need to open your documents in the order you want to join them - script will move pages from 2 to Nth Document at the end of the 1st open document - you also need to make your "first" Document Active.

So, if you have ~30 docs - you should to do it in batches - just in case - let's say 5 docs at a time - and then save after each batch - so you'll have to repeat only last failed attempt - not everything from sratch.

So, you should open docs 1-5, switch to doc 1 and run script.

Then, after processing - save your 1st doc with a NEW NAME - "something_01-05", then open docs 6-10 - run script, save your "something_01-06" file as ""something_06-10", and so on.

You have two extra options:

var CheckIfEven = true;
var RemoveSections = true;

First - will add blank pages so each document will start on the RIGHT.

Second - will remove Sections after moving pages.

When BOTH set to False - 2nd doc starts on the left - page 2 with Section marker - and 3rd doc starts on the new spread - page 5:

When RemoveSections=true - as above but without "spaces":

And when both set to true:

(numbers represent number of pages in the joined documents - for my testing)

Also attached - but you will have to change ".TXT" to ".JSX" after downloading and saving to your scripts folder.
