This tutorial explains how to backup Slack and export channels, message history, and files. In this article, I will explain some easy methods to do that. I have added some desktop and online tools in the below post to perform Slack backup. You can use these tools to quickly get all public, private conversions along with the files. But some of them can only get you the conversion history. You can download the conversation history in HTML, CSV, and text format and then do whatever you like. All these tools are completely free to use and you can use them right on your PC to get backup of your Slack data.

In the free plan, Slack only lets you export data in standard form. And that the data archive that it gives you only contains public channels and groups. The worst part is that the data files are in JSON format which are pretty hard to read to normal user. That’s where the tools that I have listed below help you. You can get all data from your Slack workspace on your PC and in easily readable form. Here I will talk about a Slack bot and a command line tool to export Slack data.
