Confusion with Mp3tag

ok I have a problem I'm new to metataging, I have a Title Colum that has both the Artist and Title in it. I want to remove the artist and leave only the title how can this be done i have over13,000 Mp3 files to edit

Could you show us a real example of one of those titles, preferably a screenshot?
And: are we really talking about the TITLE or is it the filename?

You have to search for a unique dividing character between your ARTIST and TITLE. A common character is a dash -

Then you can use Convert -> Tag - Tag. This way you can immediately see a preview of the result.

As soon as you show us a screenshot, we can help you finding this dividing character and suggest a working format string.

In your case, there is no dividing character in the TITLE tag.

BUT:
You can use the current filename and Convert -> Filename - Tag with a format string like
%ARTIST% - %TITLE%

As the data us much better structured available in the filename, please use in MP3tag
Convert>Filename-Tag
Format string: %artist% - %title%

This won't change anything in my file name column I only want to change what's in the title column

Yes, indeed. this won't change the filename.
But it imports data from the filename into the fields ARTIST and TITLE.

Please take care that you use Conver>Filename-Tag and not Convert>Tag-Filename.

Thank you very much that helped me
