Reply To: Redefine Paragraph and Character Style Script?

Not sure this will work as I don’t have access to ID currently and am a bit rusty, but I would try something along the lines of:

var myPars = app.document.paragraphs.everyItem();

for (var num = 0; num < myPars.length; num++) {
var revisedPointSize = myPars[num].texts.anyItem().pointSize;
myPars.appliedParagraphStyle.pointSize = revisedPointSize;
}

It could be made more elegant by skipping styles already fixed, or I could be approaching it totally backward or incorrectly, but that’s how I would start. This only accounts for point size and not other properties that might be changing, or character styles, but hopefully it helps you start to tackle it.
