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
#EXTINFentries 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
- Paste your M3U text or upload a local
.m3ufile. - Click Validate Playlist.
- 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.
