Script to always save IDML with INDD


Is there an existing script for InDesign that will save an INDD file and an IDML copy at the same time?

I work with dozens of independent designers on collaborative projects, and those of us with Creative Cloud have to remember to save an IDML copy for those on earlier versions. And we often forget.

I'm hoping to find or tweak a script that will, for instance, add a menu item called, say, 'Save with IDML', and will save both the current document and an IDML copy alongside it.

Accepted Answer

This example should get you started. You need to run the script once per InDesign session. You could add it as a startup script for example. It will save everytime the user saves the document a idml file.

#targetengine "session"
// we need a targetegine to make this work
var doc = app.activeDocument; // get the current doc

// now to the event listener
app.addEventListener('afterSave', function(theEvent) {
  $.writeln('saving'); // just to see whats going on
  if (!doc.saved) {
    // catch those possible mistakes
    alert('doc was never saved');
  var aName =; // get the name
  var newName = aName.replace("indd", "idml"); // replace the indd to idml
  // crate a new File Object next to the indd
  var theFile = File(File(doc.filePath).fsName + "/" + newName);
  // export
  doc.exportFile(ExportFormat.INDESIGN_MARKUP, theFile, false);

If you want this as a menu command you could take look into this blog post on indiscripts.

Thanks, @fabiantheblind, that works brilliantly. I've adapted that to make it work as a Startup Script (it waits for a document to be opened).

// Set a targetengine to make this work
#targetengine "session"

function saveIDML() {
    // Exit if no documents are open.
    if(app.layoutWindows.length == 0) {
    } else {
        // Get the current document
        var doc = app.activeDocument;
        $.writeln('Saving IDML of ' + doc + ' ...');
        // Catch errors
        if (!doc.saved) {
          alert('Sorry, there was a problem and the document was not saved.');
        // Create a new .idml file name from the .indd file name
        var inddName =;
        var idmlName = inddName.replace("indd", "idml");
        // Create the new .idml file next to the .indd file
        var theFile = File(File(doc.filePath).fsName + "/" + idmlName);
        doc.exportFile(ExportFormat.INDESIGN_MARKUP, theFile, false);
// Listen for the save event
app.addEventListener('afterSave', saveIDML, false);
