How to Validate an M3U Playlist

Use the M3U validator to catch duplicates, dead entries, and malformed lines before you load a playlist.

What the validator checks

  • Total channels - how many #EXTINF entries were found.
  • Valid entries - entries with a following, non-comment URL.
  • Invalid entries - entries missing a usable URL.
  • Duplicates - repeated channel names.
  • Missing metadata - entries without channel names or group info.
  • Malformed - entries that break the expected structure.

How to use it

  1. Paste your M3U text or upload a local .m3u file.
  2. Click Validate Playlist.
  3. Review the stats and fix flagged issues in your file.

Privacy

Validation runs entirely in your browser. Your playlist text is never uploaded or stored.

Tip: validate after editing a playlist and before importing it into a player.
