There is a find-replace question in the .vtt file that I want to convert to .srt file.

00:00:00.340 --> 00:00:02.800
(SINGING) You started with
a string you need validated.

00:00:02.800 --> 00:00:05.660
Used conditionals, and
things got complicated.

in order to make a valid .srt file, I wanna turn all the “.” in timeline into "," ▼

▲ (?:\d{2}:\d{2}:\d{2})(.)(?:\d{3})

But it just doesn't work in the macro~

You’re very close. Try this regex, which uses lookbehind and lookahead instead of non-capturing parentheses, and see if it doesn’t work for you:

(?<=\d{2}:\d{2}:\d{2}).(?=\d{3})

It works and thank you so much~~ This is my first time to ask questions here in the KM forum. It’s so great! I gotta learn some “lookbehind and lookahead” related stuff:grin:
