If line begins with whitespace, all text lost

[wordsmith189]

Hi! I'm excited to use YouTube transcripts, then convert to TextGrid... Your script (thanks!!) works with the demo srt file (Katie) but my srt file, attached here, won't work. I assume because lines start with blank space? They were induced when I used an online converter to go from sbv to srt. (I think YouTube only outputs sbv these days?)

Any idea if this is fixable?
