Rename Photoshop document using text from a text layer

Another option is to use the cross-platform ExifTool CLI utility – however, it all depends on how many text layers there are and in which position the target text layer falls etc.

This example assumes a single text layer and uses the text layer name:

exiftool '-FileName<${XMP-photoshop:TextLayerName}.%e' '/Users/user/Mac OS Path to/Folder-Of-Files-To-Rename'

This example assumes a single text layer and uses the text layer content:

exiftool '-FileName<${XMP-photoshop:TextLayerText}.%e' '/Users/user/Mac OS Path to/Folder-Of-Files-To-Rename'

Windows users would swap the ' single straight quote marks for " double straight quote marks and use an appropriate file system syntax.

Whether using a script or ExifTool command line code, it is probably a good idea to add-in extra code to save the current filename to the XMP-xmpMM:PreservedFileName metadata, just in case you wish to undo the rename and get back to the original filename. One can always use Adobe Bridge Batch Rename Tool to bulk populate the preserved filename metadata into each file, before renaming using another method.

This takes the contents of the topmost text layer and renames the file based on that. You'll want to further refine it as this is prety basic.

#target photoshop
renameFromTextLayer();
function renameFromTextLayer(){
try{
if(documents.length > 0){
var originalDialogMode = app.displayDialogs;
app.displayDialogs = DialogModes.ERROR;
var docRef = activeDocument;
var layerText = '';
for(var i = 0; i < docRef.artLayers.length; i++){
var LayerRef = docRef.artLayers[i];
if(LayerRef.kind == LayerKind.TEXT){
layerText = LayerRef.textItem.contents;
break;
}
}
var psFile = File(docRef.fullName);
var psFileName = psFile.name.split('.');
if(psFileName.length > 1){
layerText = layerText + '.' + psFileName[psFileName.length - 1];
}
docRef.close();
psFile.rename(layerText);
}
app.displayDialogs = originalDialogMode;
}
catch(e){
alert(e + e.line);
app.displayDialogs = originalDialogMode;
}
}
