Modification of tags for mp4 and case conversion

When I want to renew track on M4a music, renew track number with 0 first seems not working (for me)

Converting text like function proper in Excel (Example : I don't speak english --> I Don't Speak English)

Could you help me ?


MP4 tags do not allow leading 0 in TRACK.

Merci beaucoup.
I'll try.
