I would like to change the Title tag in my audio files.
I'd like to replace all spaces between numbers with a colon.
Examples:
abc 232 3 sd BECOMES abc 232:3 sd
alk sdfwe wer 3 32 sdf asdf BECOMES alk sdfwe wer 3:32 sdf asdf
s asfwe wqerqwer qwr 232 432 asd we re BECOMES s asfwe wqerqwer qwr 232:432 asd we re
I appreciate your help.
Ken

Try the function "Replace with regular expression":
_Field:_
**TITLE**
_Regular expression:_
**([0-9]+)(\s)([0-9]+)**
_Replace matches with:_
**$1:$3**
[] _case-sensitive comparison_
And let us know, if it works for you. 😉
