This is a very handy tool! One improvement I would love to see is the ability to cache/save data locally, so it doesn't depend on loading from Slack. If the Slack account goes away, or reduced from paid to free, this could be a problem and data may be lost.
You might be able to leverage the output of this project (https://github.com/grundleborg/slack-advanced-exporter) which downloads attachments and adds them to the export archive in a '__uploads' folder. Maybe it could be as simple as changing the location your tool loads attachments from, instead of the 'https://files.slack.com...' resources.

Thanks for all your hard work on this tool!
