I know this maybe a topic that has come up a few times but I could not find a direct answer. Is there a way to bulk rename tags in Calibre? Maybe log that contains them all? A tool I am not familiar with? I did set a rule to Capitalize the tags but what if you have a bunch that are all lower case titles and want them to be upper case titles? Do I have to use the Tag editor to do each one?

I have started to remove all the junk ones but I have thousands that are not done right in terms of title cases. Any help would be great.
