Mass Edit of Charactor

Is there an easier way to apply a mass edit to change from ; (Semi Colon) to \ (Double Back Slash)for Artist and Artist Sort fields.
Example: George Michael; Elton John - Change to George Michael\Elton John
and same in artist sort field, John, Elton; George, Michael - John, Elton\Michael, George.

My end point music player is not showing artists correctly. I Have tried a test few files and when I have changed the charactors, music player shows correct name displays.

I dread having to change individually.
Thanks

Use an action of the type "Replace" for ARTIST and in a second run for ARTISTSORT.

Where do you see the semicolon and where the double backslash?
The double backslash in MP3tag usually indicates that there are several fields of the same type, e.g. ARTIST - but only very few players can cope with these.

I use ASSET from DBPowerAmp on my Synology Server. If files have semi-colon set between multiple artists it will only show first artist. If files have double back slash it will show both artists, also in searching both artists appear under their own name, for example, George Michael(Double back slash)Elton John.
The reason for the mass edit is to be able to change from semi colon seperator to double back slash in one go, rather than individually.

And? Have you tried the action of the type "Replace"?

Alternatively, you could use an action of the type "Split field by separator"

Thanks for quick reply.
Any chance of an idiots guide in how too?

In many cases the Howtos and FAQs help in such basic topics:

shows how to create an action.

Load the files
select the files
Use Actions(Quick)
Select as action "Split by seaprator.
Select as field ARTIST
Set as separator ;

Thanks for your help, I have managed to create replace action as you suggested.
