How can I use this dear?
Please help me! I was using a site droidvision and was doing the job well to convert my m3u playlist to Json, but the site is not responding and it possibly down for long.
After searching in google on how to convert an m3u to Json I found this script but no documentation or tip. Can you please tell us how to use it?
Many thanks.
