Public dataset
https://github.com/houstondatavis/slack-export
Contains public channels and user data exported from [houstondatavis.slack.com] on July 31st, 2016. Data is organized in folders for each channel, each folder contains .json file for certain period of conversation. These can be easily imported to other worskspaces throught Administration>Workspace Settings>Import Data (although they will get archived so they won't be seen until moving them to active channels). Unfortunately (after counting messages per user) it doesn't seem like this export contains enough full-fledged conversations to make use of later on when more advanced features will be implemented. On the other side, they will be sufficient for earlier stages.
The workspace contains 16 channels and 75 users. Apart from messages, .json files contain:
- list of users (the product of conversations.list method)
- list of channels (the product of users.list method)
- channel join and leave times
- upvotes and downvotes on messages
- changes of channel topic
