What Exactly Are External Tools in Power BI?

External tools are standalone applications that can be launched directly from the Power BI Desktop interface. When started from the "External Tools" ribbon, they gain access to the internal data model (the Analysis Services engine) running behind your Power BI report. This connection allows them to perform advanced operations that aren’t possible within the standard Power BI user interface.

Think of them as plug-ins that supercharge your Power BI development experience. Some of the most popular and invaluable tools include:

• Tabular Editor: An advanced tool for editing Power BI data models. It allows batch editing, scripting with C#, and implementing advanced modeling techniques.
• DAX Studio: An essential utility for anyone serious about writing and optimizing DAX (Data Analysis Expressions). It helps you analyze query performance, browse your data model, and troubleshoot complex formulas.
• ALM Toolkit: A schema comparison tool for managing Application Lifecycle Management (ALM). It’s perfect for comparing different versions of a Power BI file and managing deployments.

By integrating these applications, you effectively create a more robust and professional development environment right within Power BI Desktop.

Why Bother Adding External Tools?

You might be getting along just fine with the native features of Power BI Desktop. So why introduce more tools? The simple answer is efficiency and capability. While Power BI is user-friendly, it sometimes hides the complexity needed for enterprise-grade solutions. External tools unlock this deeper level of control.

Key Benefits of Using Them

• Faster DAX Development: Tools like DAX Studio provide a far superior environment for writing, debugging, and optimizing DAX queries compared to the small formula bar in Power BI. You can view query plans and performance metrics to pinpoint bottlenecks.
• Advanced Data Modeling: Tabular Editor offers powerful features like implementing calculation groups, perspectives, and translations, none of which can be done in the standard Power BI interface. It also lets you script changes, saving hours on repetitive tasks.
• Performance Optimization: You can dive deep into how your data model is compressed and stored in memory using DAX Studio’s VertiPaq Analyzer. This helps you identify large columns or tables that could be slowing down your report.
• Better Governance and ALM: ALM Toolkit is critical for team-based development. It enables you to compare PBIX files, identify changes, and merge them, bringing version control practices to your Power BI projects.
• Improved Productivity: Ultimately, these tools save you time. They automate tedious tasks, provide deeper insights for troubleshooting, and streamline complex development processes.

Getting Started: Prerequisites You'll Need

Before you jump in, there are a few things you need to have in place. The good news is, the list is short and straightforward.

1. Power BI Desktop: You’ll need an up-to-date version of Power BI Desktop installed. The External Tools ribbon feature was introduced in the July 2020 release, so any recent version will work perfectly.
2. The External Tools Themselves: You must download and install the external tools you want to use on the same machine as Power BI Desktop. We’ll cover where to get the most popular ones below.
3. Admin Rights (Sometimes): You may need administrator privileges on your computer to install these applications.

That’s it! As long as you have Power BI Desktop and the tools are installed correctly, you’re ready to go.

How to Add Community-Recognized Tools (The Easy Way)

The Power BI user community has created some amazing tools, and the most popular ones feature simple installers that automatically register themselves with Power BI Desktop. DAX Studio, Tabular Editor 2, and ALM Toolkit all fall into this category. The process is incredibly simple.

Let’s use DAX Studio as an example:

1. Shut Down Power BI Desktop: Before installing any external tool, make sure all instances of Power BI Desktop are closed. This ensures the installation process can complete smoothly without file conflicts.
2. Download the Installer: Go to the official DAX Studio website (daxstudio.org) and download the latest version of the application.
3. Run the Installer: Open the downloaded file and follow the on-screen prompts. The standard installation options are perfectly fine for most users. During installation, the tool will automatically detect your Power BI Desktop installation and add the necessary configuration files.
4. Launch Power BI Desktop: Once the installation is complete, open your Power BI Desktop file.
5. Find the External Tools Ribbon: Navigate to the External Tools tab in the Power BI ribbon. You should now see an icon for DAX Studio waiting for you.

Clicking the DAX Studio icon will launch the application and automatically connect it to the data model of your currently open PBIX file. The process is identical for Tabular Editor 2 and ALM Toolkit - just download, run the installer, and you’re done.

Manually Adding an External Tool with JSON

What if you want to add a tool that doesn’t have an automatic installer, or you want to add a custom shortcut, like one to a useful website or a portable app? Power BI lets you do this by manually creating a specific JSON configuration file.

Power BI Desktop looks for files ending in .pbitool.json in this specific folder:

C:\Program Files (x86)\Common Files\Microsoft Shared\Power BI Desktop\External Tools

Any valid .pbitool.json file you place in this directory will appear as a button in the External Tools ribbon upon restarting Power BI Desktop.

Understanding the JSON File Structure

The JSON file contains a few key properties that tell Power BI Desktop what to name the button, where to find the application, and how to display it. Here’s a breakdown of a typical structure:

{
  "version": "1.0",
  "name": "My Custom Tool",
  "description": "A description that appears on tooltip.",
  "path": "C:\\Path\\To\\Your\\Application.exe",
  "arguments": [
    "%server%",
    "%database%"
  ],
  "iconData": "image/png,base64,iVBORw0KG..."
}

• name: (Required) This is the text that will appear on the ribbon button.
• path: (Required) The full, absolute path to the executable file (.exe) you want to run. Remember to use double backslashes (\\) or a single forward slash (/) for the path separators in JSON.
• description: (Optional) This text appears as a tooltip when you hover your mouse over the button. It’s great for reminding yourself what the tool does.
• arguments: (Optional) This is where the magic happens. Here you can pass command-line arguments to the tool you’re launching. Power BI provides special placeholders:
• iconData: (Optional) This allows you to add a custom icon to your button. You need to provide a Base64-encoded image string. You can use an online converter to turn a PNG image into this string. If you omit this, Power BI will use a generic default icon.

Example: Adding the Monkey’s Copy Tool Manually

Let’s create a .pbitool.json for a handy little tool called "Monkey’s Express Copy" which allows you to quickly copy table contents from DAX Studio to your clipboard.

1. Open a text editor like VS Code or Notepad.
2. Create a file with the following contents. Make sure to update the "path" to reflect where you installed or unzipped the tool.

{
    "name": "Monkeys Express Copy",
    "description": "Copy Tables from DAX queries to clipboard.",
    "path": "C:\\Tools\\MonkeysExpressCopy.exe",
    "iconData": "data:image/png,base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQBAMAAADt3eJSAAAAMFBMVEU0OkArMTRCSkVJUFZRV1xlZmlsbXBxdXR/gYeLj5LNztHS1NXW2Nrp7e/x8vP5+fvy8/b2YJgWAAAAAXRSTlMAQObYZgAAAElJREFUCNdjYKAuuELFyEBEVFL21GJgYBBkOMzu7u6enm7+znZ2ln8/RxQU5ORlFBRlFBWkAgz29/f3dna2s7AwMLAwgAYiIB0CACYkCoK0JSgHAAAAAElFTkSuQmCC"
}

1. Save this file as MonkeysExpressCopy.pbitool.json.
2. Move the file to the Power BI external tools folder: C:\Program Files (x86)\Common Files\Microsoft Shared\Power BI Desktop\External Tools.
3. Restart Power BI Desktop. The "Monkeys Express Copy" tool will now be available in your toolbar!
