Reply To: Change to LowerCase

I came up with this:

//Change to Uppercase to Lowercase

app.findGrepPreferences = app.changeGrepPreferences = null;
app.findGrepPreferences.properties = ({findWhat:"[A-Z]"});
app.findGrepPreferences.appliedCharacterStyle = "Letter ID";
found = app.activeDocument.findGrep();
for (i = 0; i < found.length; i++)
found[i].characters[0].changecase (ChangecaseMode.lowercase);


Though it works fine, can someone check if it needs any improvement?

Thanks in advance.
