    Article summary

    With Rocket.Chat's import feature, you can import your Slack users, channels, messages, and other data to your workspace. This page guides you through the required steps.


    • Permission to export Slack data.

    • Permission to import data to Rocket.Chat workspace.

    Before importing, keep the following points in mind:

    • If your Slack workspace is currently set up to hide emails, they'll also be excluded from exports. You can update your workspace settings temporarily and re-run the export to include emails as well.

    • It can be helpful to export time ranges from Slack such that the size of each import file is less than 15MB.

    • If facing difficulties during the upload phase of the import process, try copying the archive directly to the uploads folder using other means such as scp. Then select Server File Path as the File Type.

    • Channel name with special character: If you use special characters in the channel name, it is important to enable the option "Allow Special Characters in Room Names" in layout settings. An advanced option is to edit the special characters accepted in the UTF-8 setting in the general configuration. For example: [0-9a-zA-Z-_.ãÃàèìòùÀÈÌÒÙáéíóúýÁÉÍÓÚÝâêîôûÂÊÎÔÛãñõÃÑÕäëïöüÿÄËÏÖÜŸçÇßØøÅåÆæœ]+$

    • If you import a Slack user with the same username as in your Rocket.Chat workspace, the Slack user is not imported.

    • If you import a Slack channel with the same name as in your Rocket.Chat workspace, the messages from Slack are imported into the existing Rocket.Chat channel.

    Export Slack data

    Once your data is ready, go to the next steps to import it into your workspace.

    Import Slack data

    In your Rocket.Chat workspace, go to Administration > Workspace > Import. The Import page lists the import history.

    1. Click Import New File.

    2. For the Import Type field:

      1. Select Slack to import your entire workspace data.

      2. Select Slack's Users CSV to import the users only.

    3. Select one of the following options for the File Type field:

      1. Upload: Upload the exported data as a .zip file.

      2. Public URL: Enter the file URL.

      3. Server File Path: Enter the file path.

    4. Click Import.

      1. If you are importing your entire Slack workspace data, the users, channels, and messages tabs are displayed. Deselect the Users and Channels you do not want to import. By default, all messages from the selected users and channels are imported.

      2. If you are importing only your Slack's Users CSV, the list of users is displayed. You can deselect the users that you do not want to import.

    5. Click Start Importing. Once the import is successful, you can view the import details on the Import page.

    After import

    Now that your Slack data has been successfully imported, you can take the following steps to verify your data:

    1. Go to Administration > Workspace > Users. Check that your Slack users are present. Note that the Workspace Admin role of a Slack user is inherited in Rocket.Chat as admin. Other users have the user role.

    2. Use the search option to search for the imported channels. You can see the imported messages in the channels.
