Slack Export Viewer

Build Status PyPI version

A Slack Export archive viewer that allows you to easily view and share your Slack team's export (instead of having to dive into hundreds of JSON files).

Preview

Contents

Overview

slack-export-viewer is useful for small teams on a free Slack plan (limited to 10,000 messages) who overrun their budget and ocassionally need a nice interface to refer back to previous messages. You get a web interface to easily scroll through all channels in the export without having to look at individual JSON files per channel per day.

slack-export-viewer can be used locally on one machine for yourself to explore an export or it can be run on a headless server (as it is a Flask web app) if you also want to serve the content to the rest of your team.

Installation

I recommend pipsi for a nice isolated install.

pipsi install slack-export-viewer

Or just feel free to use pip as you like.

pip install slack-export-viewer

slack-export-viewer will be installed as an entry-point; run from anywhere.

$ slack-export-viewer --help
Usage: slack-export-viewer [OPTIONS]

Options:
  -p, --port INTEGER        Host port to serve your content on
  -z, --archive PATH        Path to your Slack export archive (.zip file or
                            directory)  [required]
  -I, --ip TEXT             Host IP to serve your content on
  --no-browser              If you do not want a browser to open
                            automatically, set this.
  --channels TEXT           A comma separated list of channels to parse.
  --no-sidebar              Removes the sidebar.
  --no-external-references  Removes all references to external css/js/images.
  --test                    Runs in 'test' mode, i.e., this will do an archive
                            extract, but will not start the server, and
                            immediately quit.
  --debug
  --help                    Show this message and exit.

Usage

1) Grab your Slack team's export

2) Point slack-export-viewer to it

Point slack-export-viewer to the .zip file and let it do its magic

slack-export-viewer -z /path/to/export/zip

If everything went well, your archive will have been extracted, processed, and browser window will have opened showing your #general channel from the export.

CLI

There is now a CLI included as well. Currently the one command you can use is clearing the cache from slack-export-viewer from your %TEMP% directory; see usage:

└———→ slack-export-viewer-cli --help
Usage: slack-export-viewer-cli [OPTIONS] COMMAND [ARGS]...

Options:
  --help  Show this message and exit.

Commands:
  clean  Cleans up any temporary files (including...

Examples

┌— hamza@AURORAONE C:\Users\hamza
└———→ slack-export-viewer-cli clean
Run with -w to remove C:\Users\hamza\AppData\Local\Temp\_slackviewer
┌— hamza@AURORAONE C:\Users\hamza
└———→ slack-export-viewer-cli clean -w

Acknowledgements

Credit to Pieter Levels whose blog post and PHP script I used as a jumping off point for this.

Improvements over Pieter's script

slack-export-viewer is similar in core functionality but adds several things on top to make it nicer to use:

  • An installable application
  • Automated archive extraction and retention
  • A Slack-like sidebar that lets you switch channels easily
  • Much more "sophisticated" rendering of messages
  • A Flask server which lets you serve the archive contents as opposed to a PHP script which does static file generation
You can’t perform that action at this time.
