Looking for a PNG script

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.");
}
