You can install the Struct bot in Slack: https://struct.ai/install-slack -- This would by default pick up the last 3 months of conversations (we do this to decrease the unpaid load on GPT). You can ping us and we can help sync it from the beginning of whatever history Slack shows.

We don't have an exporter yet, but can surely put one together which provides a SQL / CSV formatted output (or whatever works best for users). We would never charge for exports.
