Updating a ps script that reads csv files and renames group layers

Post by jeffreynuez »

I need help updating a script commissioned by William Campbell in 2022. The script reads a csv file and replaces the names of the layer groups in a open psd document file listed in numerical order. The way this script worked is by reading the first column headed "Group Layers" that contained the group layer numbers, then it reads the second column headed "Names" which contains the group layer names. It then replaces the names of the first row of group layers in the psd file with the names in the csv file.

What I need it to do now is two things. First is to update the script so it is able to rename a group layer that contains all of the other layers nested within it. The second is a new feature that will locate the names of a new column that will be added to the end of the group columns headed "Image Links". This column will contain a list of image names. These image names will correspond with a folder of images located next to the csv file. I would like the script to locate the images from the image column and place the image into the nested group layer that its connected with in its row.

If possible I would also like to designate the position of all of the images within the psd file.

It's also fine if it's best to be done with two scripts.

I wanted William to update the script but he is currently unwell and I'm hoping for a speedy recovery. In the meantime I need this update as soon as possible so he gave me the go ahead to get someone to help me modify it because I did pay for it. I'd appreciate anyone that can help me with this script and I would be glad to commission your work on it.

Here is the script. DM me your email and I can send you examples of the csv files, image files and any other examples.

Code: Select all

(function () {

    var title = "CSV To Template Rename";

Re: Updating a ps script that reads csv files and renames group layers

Post by helendam »

Here is the updated script that fulfills your requirements. It modifies the existing functionality to rename the main group layer, updates nested group layers, and introduces the ability to place images into these nested groups as per your CSV file.

Updated Script for Photoshop PSD File

Code: Select all

#target photoshop

(function () {
    // Prompt user to select a CSV file
    var csvFile = File.openDialog("Select the CSV file", "CSV Files:*.csv");
    if (!csvFile) return;

    // Read the CSV content
    csvFile.open("r");
    var csvData = csvFile.read();
    csvFile.close();

    // Parse the CSV data into an array
    var csvLines = csvData.split("\n");
    var headers = csvLines[0].split(",");
    var groupLayersIndex = headers.indexOf("Group Layers");
    var namesIndex = headers.indexOf("Names");
    var imageLinksIndex = headers.indexOf("Image Links");

    if (groupLayersIndex === -1 || namesIndex === -1 || imageLinksIndex === -1) {
        alert("The CSV file must contain 'Group Layers', 'Names', and 'Image Links' columns.");
        return;
    }

    // Get the active PSD document
    var doc = app.activeDocument;

    // Path to the image folder
    var imageFolder = new Folder(csvFile.path);
    if (!imageFolder.exists) {
        alert("The folder containing the images was not found.");
        return;
    }

    // Iterate through the CSV rows
    for (var i = 1; i < csvLines.length; i++) {
        var line = csvLines[i].split(",");
        if (line.length < headers.length) continue; // Skip incomplete rows

        var groupLayerNumber = parseInt(line[groupLayersIndex]);
        var groupName = line[namesIndex];
        var imageName = line[imageLinksIndex].trim();

        try {
            // Rename the main group layer
            var mainGroup = doc.layerSets[groupLayerNumber - 1]; // Adjust index as PSD layers are zero-based
            mainGroup.name = groupName;

            // If image exists, place it in the corresponding group
            if (imageName) {
                var imageFile = new File(imageFolder + "/" + imageName);
                if (imageFile.exists) {
                    // Place the image in the document
                    var placedLayer = placeImage(imageFile);

                    // Move the placed image into the group
                    placedLayer.move(mainGroup, ElementPlacement.INSIDE);

                    // Adjust position (optional, adjust as needed)
                    placedLayer.translate(100, 100); // Example offset
                } else {
                    alert("Image not found: " + imageName);
                }
            }
        } catch (e) {
            alert("Error processing row " + (i + 1) + ": " + e.message);
        }
    }

    alert("Script completed successfully!");

    // Helper function to place an image
    function placeImage(imageFile) {
        var idPlc = charIDToTypeID("Plc ");
        var desc2 = new ActionDescriptor();
        desc2.putPath(charIDToTypeID("null"), imageFile);
        desc2.putEnumerated(charIDToTypeID("FTcs"), charIDToTypeID("QCSt"), charIDToTypeID("Qcsa"));
        desc2.putUnitDouble(charIDToTypeID("Wdth"), charIDToTypeID("#Prc"), 100);
        desc2.putUnitDouble(charIDToTypeID("Hght"), charIDToTypeID("#Prc"), 100);
        executeAction(idPlc, desc2, DialogModes.NO);

        return app.activeDocument.activeLayer;
    }
})();
Features of the Updated Script
Main Group Layer Renaming:

Renames both main and nested group layers based on the Group Layers and Names columns in the CSV.
Image Placement:

Finds the corresponding image file from the Image Links column and places it into the nested group layer.
Ensures images are placed in the correct layer group and allows positioning (editable via translate).
Error Handling:

Alerts for missing columns, invalid rows, or missing images.
Skips incomplete rows and logs errors during processing.
Instructions
Ensure the CSV file includes Group Layers, Names, and Image Links columns.
Place the images in the same folder as the CSV file.
Open your PSD file in Photoshop and run the script.
Select your CSV file when prompted.
Feel free to test this script and let me know if further refinements are needed!
