Best approach to read and export channel names? Ideally into a database of some sort.

@virakones 

I'm not sure if this is the "best approach", but it's "an approach"... I had all the bits required from other scripts, so it was just a case of a few copy/pastes and some refactoring. The CSV will be written to the desktop using the active Photoshop document name as a prefix:

/*

#target photoshop

var os = $.os.toLowerCase().indexOf("mac") >= 0 ? "mac" : "windows";
if (os === "mac") {
    logFileLF = "Unix";
} else {
    logFileLF = "Windows";
}
var sourceDocName = activeDocument.name.replace(/\.[^\.]+$/, '');
var logFile = new File("~/Desktop/" + sourceDocName + "_Channel Names.csv");
if (logFile.exists)
    logFile.remove();

// Loop backward to reverse channel order
//for (var i = activeDocument.channels.length - 1; i >= 0; i--) {
// Loop forward
for (var i = 0; i < activeDocument.channels.length; i++) {
    try {
        logFile.open("a");
        logFile.encoding = "UTF-8";
        logFile.lineFeed = logFileLF;
        // Doc name, channel name
        //logFile.writeln(activeDocument.name.replace(/,/g, '-') + "," + activeDocument.channels[i].name.replace(/,/g, '-'));
        // Channel name
        logFile.writeln(activeDocument.channels[i].name);
        logFile.close();
    } catch (e) {
        alert(e + ': Line ' + e.line);
    }
}

logFile.execute();
