Script to automatically make a copy of a Google Document for editing

You can certainly do this with Apps Script. Only takes a couple of lines. In fact, you can use just the version I wrote below.

Here is how I would do it -

1. Ensure you original document is at least read enabled for the folks that will be accessing it.

   

2. Grab the fileId from the URL -

   

3. Write a web app in Apps Script with the following code -

   function doGet(e) {
     //file has to be at least readable by the person running the script
     var fileId = e.parameters.fileId;  
     if(!fileId){
       //have a default fileId for testing. 
       fileId = '1K7OA1lnzphJRuJ7ZjCfLu83MSwOXoEKWY6BuqYitTQQ'; 
     }
     var newUrl = DocsList.getFileById(fileId).makeCopy('File copied to my drive').getUrl(); 
     return HtmlService.createHtmlOutput('<h1><a href="'+newUrl+'">Open Document</a></h1>');
   }
   

4. Deploy it to run as the person accessing the app.

   

One key thing to remember is that a web app built by Apps Script cannot force open a new window automatically. Instead we can show a link which is clickable into the document in edit mode.

You can see it in action here (will create some dummy file) -

You can test this by putting in your own fileId.

Since DocsList is deprecated, currently you can make a copy of a file using the following code:

File file=DriveApp.getFileById(fileId).makeCopy(fileName, folder);

where fileId can be obtained as explained in the answer by Arun Nagarajan.
