How to get channel profile list?

I want to get all channel profiles.
How do I get profile information without knowing the channel ID?
Or is there a way to get a list of channel IDs?

I cannot do English well. sorry.
thanks

No thats not possible. Technially channel IDs go from 1 to infinity
It’s also technically impossible to extract Twitch whole Users database

If you have the username, you can lookup a user by login
