How to add space before character in file name

How do i add a space before the charater {Clean} in this file name Aidonia - Cyan Done{Clean} i have tried replace {Clean} with space infront then {Clean} but that those not work any one have any assistant they can offer

That works for me with Convert Tag -> Tag and this Format string for the assumed TITLE content:
$replace(%TITLE%,{Clean}, {Clean})

If this does not work for you, please provide a screenshot showing what you tried.

BTW:
If you are using a Mac and the above Format string does not work, please select the Mac category and tell us about your MacOS- and Mp3tag versions.

You can use Convert → Tag - Filename using Formatstring

$replace(%_filename%,{Clean}, {Clean})

Alternatively, you can use a (Quick) Action Replace


Moving this to Mac
