What you'll see

Your chat opens as its conversation, each message in a bubble in its sender's color, with the days, replies, reactions and calls, and the photos and voice notes the export holds.

About Slack

A Slack workspace's owners and admins can export its messages from the workspace's settings, as a ZIP: users.json and channels.json at the top, and a folder for each conversation with a JSON file for each day. Every plan exports public channels, and Business+ and Enterprise Grid owners can export private channels and direct messages too.

Teams export a workspace when they move to another tool, close it or must keep its records. Slack can import an export into another workspace, but no app shows one, and its days are hundreds of small JSON files.

Filepeek reads the ZIP into its channels and conversations, each message under its author, with threads, reactions, edits and mentions by name. Search counts every match, a date jumps to its day, Stats shows who wrote how much and when, and Export saves a conversation as PDF, CSV or text. Files stay on Slack's servers, so the export only names them.

Questions

How do I export a Slack workspace?

An owner or admin opens the workspace's settings, then Import & Export Data and Export, and Slack emails a link to the ZIP once it's made.

Why are there no files or pictures?

Slack keeps a workspace's files on its servers and the export only links to them, so each shows by its name and size.

Can I read direct messages?

When the export holds them. An export of public channels has only those, and an owner's full export adds private channels and direct messages.
