Renaming multiple artboards/layers, specifically removing the word copy.

Also when building a multi-variat campaign, I'll drag a copy of all the selected artboards over, but this adds "copy" and then "copy copy" or "copy2" Ideally it would be great if I could just have a list of the artboards, do the whole find and replace thing and maybe make tweaks to the layer names if need be.

You will need to rename existing layers, but for new layers - double check the layers panel menu, panel options: "Add copy to copied layers and groups" and untick it.

Give this script a try:

var dialog = new Window("dialog");
dialog.text = "Layer Name Renamer";

var but1 = dialog.add("button", undefined, "Export layer names");
var but2 = dialog.add("button", undefined, "Rename layers");
var but3 = dialog.add("button", undefined, "Exit");

var doc = app.activeDocument;

var txtFile = File("/path/to/layerNames.txt");


function exportNames() {
	txtFile.open('w');

	for(i=0; i<doc.layers.length; i++) {
		txtFile.writeln(doc.layers[i].name);
		for(j=0; j<doc.layers[i].layers.length; j++) {
			txtFile.writeln(doc.layers[i].layers[j].name);
		}
	}

	alert("Layer names written to: " + txtFile);
}

function renameLayers() {
	txtFile.open('r');

	var layerNames = txtFile.read().split("\n");

	var c = 0;

	for(i=0; i<doc.layers.length; i++) {
		doc.layers[i].name = layerNames[c];
		c++;
		for(j=0; j<doc.layers[i].layers.length; j++) {
			doc.layers[i].layers[j].name = layerNames[c];
			c++;
		}
	}

	alert("Layers renamed");
}

function endScript() {
	dialog.close();
}


but1.onClick = exportNames;
but2.onClick = renameLayers;
but3.onClick = endScript;

dialog.show();

Before you execute the script, make sure to create an empty text file and update the path to it inside the script. The script writes all layer names into that file like this:

This is the corresponding Layers panel inside Photoshop:

After making adjustments to the individual lines inside the text file...

 ...and running the script again, the layer names get renamed as desired:

Make sure not to change the layer order inside Photoshop between exporting and renaming layer files via the script. Have fun.
