How to Use the Playlist Checker
Open your provider panel or M3U file and copy the full text content.
Click Check Playlist to analyse the header, channel entries, and URLs.
Use a text editor to correct missing commas, remove duplicates, and standardise group-title values.
What Each Result Means
- Valid M3U Header: Your first line should start with
#EXTM3U. - Total Channels: Count of
#EXTINFentries detected. - Groups Found: Unique
group-titlevalues (or Ungrouped). - Duplicates: Repeated stream URLs (common after merges).
- Missing TVG-ID: Entries without
tvg-id, which can affect EPG mapping. - Format Errors: Basic syntax checks such as missing commas or EXTINF/URL mismatch.
Common Playlist Errors and Fixes
Usually caused by blank lines, comments, or missing URLs. Ensure every EXTINF line is followed by a stream URL line.
If an EXTINF line is missing the comma and channel name part, many players show empty names. Add the missing comma and name.
Standardise group-title values (case, spelling) so players don’t create multiple near-identical groups.
Frequently Asked Questions
No. The playlist checker runs locally in your browser. The text you paste is processed on your device and never uploaded.
Many playlists include tvg-id attributes to map channels to EPG entries. Missing tvg-id can cause guide data not to match or logos to be missing.
Duplicates usually come from merging playlists or re-adding the same URL. Remove repeated stream URLs or dedupe by channel name in an editor.
group-title is a tag that assigns a channel to a category such as News, Sports or Movies. Players use it to build groups.
It depends on your device. Very large playlists can slow down older sticks or TVs. Consider splitting by region or category if navigation becomes laggy.
