How fine-grained is the tool? Do you select a channel and export only the contents of that? Can you select only two users and only get messages between them? Or is it blunt and you simple download all data (the text makes it seem that way)?
I ask, because if it's the latter it borders on illegal to click on that button (and get ALL private conversations), at the very least it needs to be heavily regulated within the firm who can click it and how the downloaded data is stored / accessed.
It is incredibly blunt, at least for compliance exports — all you can do is export the whole workspace — and once exported it's just a ZIP of thousands of JSON files. There is no tool to look at it with. When I had to do an export I found a PHP script somebody had written to turn the JSON into thousands of HTML files, but otherwise it was grep and jq.
That sounds less promising, I had hoped you could select a single channel and export it. Or even better give permission to a user to be able to export one channel. We often have Slack channels shared with clients etc. and they have asked before to get a transcript of chats for reference. If you had fine-grained control, you could give that access to the project manager for the client in question, without having to share the access / have a central moderator handle all requests.
