How to parse Telegram channel commenters
Commenters are people who publicly reacted to a channel's posts. Here is how to start the collection, what the export size depends on, and what to do when discussions are switched off. If you specifically need the subscriber list, that is a different task — see <a href='/en/guides/mozhno-li-vygruzit-podpischikov-telegram-kanala'>can you export a channel's subscribers</a>.
Step 1. Start from the channel link
Paste the channel link — the service finds the linked discussion chat itself and starts collecting unique comment authors. No need to connect your own Telegram account, and no need to join the chat: discussions are read as open data.
Step 2. Set the depth with the limit
Depth is set by the limit — the number of recent chat messages the service reads. A higher limit reaches further back and finds more unique authors, but the run takes longer. There is no period in days here: messages are what gets counted.
Step 3. Take the export
The file contains each author's @username, the date of their first comment and their comment count, with deleted accounts filtered out. Excel and TXT, profile links clickable. The base can be saved and intersected with other collections later.
If the channel has no discussion chat
Then commenters do not exist technically — there is nothing to collect. The working workaround: use search to find neighbouring channels in the same niche with discussions enabled, or topical chats where the same audience sits.
