The Slack ODBC Driver is a powerful tool that allows you to connect with live data from Slack, directly from any applications that support ODBC connectivity.

Access Slack data like you would a database - read, write, and update Slack User, Channels, Messages, Files, etc. through a standard ODBC Driver interface.

How to create Visio diagrams from Slack Data


Automatically update Slack data with the changes you make to Visio master shapes.

Automate the process of entering data into Visio diagrams and keeping your diagrams up to date with the CData ODBC Driver for Slack. The driver surfaces Slack data as an ODBC data source that can be accessed by applications with built-in ODBC support like Microsoft Office. This article shows how to create a simple diagram to start brainstorming about Visio projects linked to Slack data.

Connect to Slack as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Slack uses the OAuth authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the Getting Started section of the help documentation for an authentication guide.

Connect Slack Data to Diagrams

Follow the steps below to use the Data Selector Wizard to import data into your diagram.

  1. Open Visio and click File -> New. Open the Brainstorming template.
  2. On the Data tab, click Link Data to Shapes.
  3. Select the ODBC option and select ODBC DSN.
  4. Select the DSN for Slack, select the table you want to import, and finish the wizard. This article uses Channels as an example.

Link Slack Entities to Shapes

Follow the steps below to create a simple diagram that shows how to create shapes from your data, one of the ways to link Slack entities to shapes:

  1. Click Brainstorming Shapes and drag a main topic onto the drawing page. Enter Channels as the text of the main topic.
  2. Click Topic.
  3. Select a row in the External Data window and drag it onto the drawing page.
  4. Right-click the Topic shape and click Data -> Edit Data Graphic.
  5. Click New Item.
  6. In the Data Field menu, select a column. In the Displayed As menu, select how to display them.
  7. Drag a few other Slack entities onto the drawing page and add association lines back to the main topic, Channels. New topics have the same configuration: Numeric columns displayed in data bars stand out in contrast to other Channels entities.

You can refresh your diagram from the Data tab, synchronizing your shapes with the external Slack data.
