Export list of all users from a group chat

Hello!

An old topic, but perhaps someone (like me) will come across it, ask themselves the same question and want a simple ready-made answer.

So, what worked for me was:

1) right click on a message from the group chat and select "copy link", then paste it to notepad and extract the Chat ID (e.g. 19:b8577894a63548969c5c92bb9c80c5e1@thread.v2)
(as described here: https://answers.microsoft.com/en-us/msteams/forum/all/get-chat-id-in-new-teams/dd9788d3-1f5a-4da4-9fc8-cc3f35f03dba )

2) go to https://developer.microsoft.com/en-us/graph/graph-explorer and sign in

3) use the command as posted by @Vasil Michev (just paste the HTTPS part): https://graph.microsoft.com/beta/chats/19:b8577894a63548969c5c92bb9c80c5e1@thread.v2?$expand=members

4) copy the response to Excel and post-process it to get the members' names, e.g. using INDEX to list every 12-th row content (with the names) and MID or SUBSTITUTE to get just the name without the "displayName" part.
