Slack Export to PDF and CSV
Open the unzipped Slack export folder, pick a channel or direct message and save it as PDF, Markdown or CSV.
No messages found. Choose the folder you unzipped from a Slack export (it holds channels.json and one folder per channel).
How to get the file
A workspace owner or admin opens Slack, Settings & administration, Workspace settings, Import/Export Data, Export, and starts an export. Slack sends a zip. Unzip it and choose the folder here. Each channel is a folder of daily .json files, and channels.json and users.json give the names. For the PDF, press Save as PDF and choose Save as PDF as the printer.
Private: nothing is uploaded
The files are read in your browser. They are not sent to any server and nothing is stored. Close the tab and it is gone.
Questions
Do I need a token or an app?
No. This works on the export file Slack gives you. No token, no app, no login.
Is it really free?
Yes. No account, no watermark, no limit on channels.
Which messages are in the export?
The free and standard plans export public channels. Private channels and direct messages need an approved export request from the owner. Whatever is in your folder is shown here.
Do you see my messages?
No. The files never leave your browser.
