I'm trying to batch process naming exported png files from InDesign. I don't want to do using a paragraph style, I want to feed Indesign a list using a script e.g.
I have 5 designs in one document:
1. I love blue
2. I love red
3. I love green
4. I love yellow
5. I love pink
I have a text list
blue
red
green
yellow
pink
I want the file names to be
blue.png
red.png
green.png
yellow.png
pink.png
I've tried using chaptgpt but I keep getting stuck in loops where it's producing pngs but it produces 25 of them! It's stuck in a weird sort of loop and files look like this:
blue.png with deisgn I love blue
blue.2png with deisgn I love red
blue3.png with deisgn I love green
blue4.png with deisgn I love yellow
blue5.png with deisgn I love pink
red.png with deisgn I love blue
red2.png with deisgn I love red
red3.png with deisgn I love green
red4.png with deisgn I love yellow
red5.png with deisgn I love pink
green.png with deisgn I love blue
green2.png with deisgn I love red
green3.png with deisgn I love green
green4.png with deisgn I love yellow
green5.png with deisgn I love pink
yellow.png with deisgn I love blue
yellow2.png with deisgn I love red
yellow3.png with deisgn I love green
yellow4.png with deisgn I love yellow
yellow5.png with deisgn I love pink
pink.png with deisgn I love blue
pink2.png with deisgn I love red
pink3.png with deisgn I love green
pink4.png with deisgn I love yellow
pink5.png with deisgn I love pink
Can anyone help me? Is there a script that already exists that I can use?
Script below as .js not supported file type for upload in this forum
// Function to read names from a text file
function readNamesFromFile(filePath) {
var file = new File(filePath);
var names = [];
if (file.exists) {
file.open("r");
while (!file.eof) {
var line = file.readln();
if (line.length > 0) {
names.push(line.replace(/^\s+|\s+$/g, '')); // Trim leading and trailing whitespace
}
}
file.close();
} else {
alert("The file does not exist.");
exit();
}
return names;
}
// Ensure the document is open
if (app.documents.length > 0) {
var doc = app.activeDocument;
// Prompt the user to select a text file containing the list of names
var file = File.openDialog("Select a text file with the list of names");
if (file === null) {
alert("No file was selected. The script will now exit.");
exit();
}
var names = readNamesFromFile(file);
// Ensure the document has the right number of pages
if (doc.pages.length != names.length) {
alert("The number of pages in the document does not match the number of names provided.");
exit();
}
// Prompt the user to select a destination folder
var destinationFolder = Folder.selectDialog("Select a folder to save the PNG files");
if (destinationFolder === null) {
alert("No folder was selected. The script will now exit.");
exit();
}
// Debugging: Log the number of pages and names
$.writeln("Number of pages: " + doc.pages.length);
$.writeln("Number of names: " + names.length);
// Loop through each page and export it as PNG
for (var i = 0; i < doc.pages.length; i++) {
var page = doc.pages[i];
var fileName = names[i] + ".png";
var filePath = new File(destinationFolder + "/" + fileName);
// Debugging: Log the page number and filename being exported
$.writeln("Exporting page " + (i + 1) + " as " + fileName);
try {
// Set PNG export preferences
app.pngExportPreferences.pngQuality = PNGQualityEnum.MAXIMUM;
app.pngExportPreferences.exportResolution = 300;
app.pngExportPreferences.pngColorSpace = PNGColorSpaceEnum.RGB;
app.pngExportPreferences.pageString = page.name;
// Export the page as PNG
doc.exportFile(ExportFormat.PNG_FORMAT, filePath);
} catch (e) {
alert("Error exporting page " + (i + 1) + ": " + e.message);
exit();
}
}
alert("Export completed successfully.");
} else {
alert("No document is open.");
}
