Power BI Connector for PowerShell
In this article you will learn how to integrate Using Power BI Connector you will be able to connect, read, and write data from within PowerShell. Follow the steps below to see how we would accomplish that. The driver mentioned above is part of ODBC PowerPack which is a collection of high-performance Drivers for various API data source (i.e. REST API, JSON, XML, CSV, Amazon S3 and many more). Using familiar SQL query language you can make live connections and read/write data from API sources or JSON / XML / CSV Files inside SQL Server (T-SQL) or your favorite Reporting (i.e. Power BI, Tableau, Qlik, SSRS, MicroStrategy, Excel, MS Access), ETL Tools (i.e. Informatica, Talend, Pentaho, SSIS). You can also call our drivers from programming languages such as JAVA, C#, Python, PowerShell etc. If you are new to ODBC and ZappySys ODBC PowerPack then check the following links to get started. |

Create ODBC Data Source (DSN) based on ZappySys API Driver
Step-by-step instructions
To get data from Power BI using PowerShell we first need to create a DSN (Data Source) which will access data from Power BI. We will later be able to read data using PowerShell. Perform these steps:
-
Install ZappySys ODBC PowerPack.
-
Open ODBC Data Sources (x64):
-
Create a User Data Source (User DSN) based on ZappySys API Driver
ZappySys API DriverYou should create a System DSN (instead of a User DSN) if the client application is launched under a Windows System Account, e.g. as a Windows Service. If the client application is 32-bit (x86) running with a System DSN, use ODBC Data Sources (32-bit) instead of the 64-bit version. -
When the Configuration window appears give your data source a name if you haven't done that already, then select "Power BI" from the list of Popular Connectors. If "Power BI" is not present in the list, then click "Search Online" and download it. Then set the path to the location where you downloaded it. Finally, click Continue >> to proceed with configuring the DSN:
PowerBiDSNPower BI -
Now it's time to configure the Connection Manager. Select Authentication Type, e.g. Token Authentication. Then select API Base URL (in most cases, the default one is the right one). More info is available in the Authentication section.
OAuth App must be created in Microsoft Azure AD. These settings typically found here https://docs.microsoft.com/en-us/graph/auth-register-app-v2. [API Help..]
Steps to get Power BI Credentials : User Credentials [OAuth]
Firstly, login into Azure Portal and there create an OAuth application:
- Go to Azure Portal and login there.
- Then go to Azure Active Directory.
- On the left side click menu item App registrations
- Then proceed with clicking New registration.
- Enter a name for your application.
- Select the account types to support with the Supported account types option.
- In Redirect URI, select Web.
- In the textbox enter https://zappysys.com/oauth as the Redirect URI or another valid redirect URL.
- Use this same Redirect URI in the Redirect URI (must match App Redirect URL) grid row.
- Copy Client ID and paste it into the API Connection Manager configuration grid in the Client ID row.
- Click on the Endpoints link and copy the OAuth 2.0 authorization endpoint (v2) URL to the Authorization URL grid row. Usually it looks similar to this:
- https://login.microsoftonline.com/daed1250-xxxx-xxxx-xxxx-ef0a982d3d1e/oauth2/v2.0/authorize
- Copy the OAuth 2.0 token endpoint (v2) URL to the Token URL grid row. Usually it looks similar to this:
- https://login.microsoftonline.com/daed1250-xxxx-xxxx-xxxx-ef0a982d3d1e/oauth2/v2.0/token
- Close "Endpoints" popup and create a Client Secret in the Certificates & secrets tab.
- Proceed by clicking New client secret and setting expiration period. Copy the client secret and paste it into configuration grid in Client Secret row.
- Now lets setup permissions for the app. Click on API Permissions and on the page click Plus Sign Add Permission
- Click on Microsoft Graph API and then choose Delegated Permissions
- on Permission list page search or choose permissions as needed. We need to enable following Permissions from 2 Sections: Microsoft Graph API and Power BI Service.
- Make sure you have checked below permissions (If you do not need Write feature then you can skip Write scopes)
offline_access Dataset.ReadWrite.All
- Click Generate Token to generate tokens.
- That's it!
Fill in all required parameters and set optional parameters if needed:
PowerBiDSNPower BIUser Credentials [OAuth]https://api.powerbi.com/v1.0/myorgRequired Parameters Authorization URL Fill in the parameter... Token URL Fill in the parameter... Client ID Fill in the parameter... Scope Fill in the parameter... Default Dataset (select after generating tokens) Fill in the parameter... Optional Parameters Client Secret Fill in the parameter... Redirect URI (must match App Redirect URI) Fill in the parameter... Default Workspace (Keep Empty for My Workspace - select after generating tokens) Fill in the parameter... RetryMode Fill in the parameter... RetryStatusCodeList Fill in the parameter... RetryCountMax Fill in the parameter... RetryWaitTimeMs Fill in the parameter... RetryMultiplyWaitTime Fill in the parameter... Login options Fill in the parameter... -
Once the data source has been configured, you can preview data. Select the Preview tab and use settings similar to the following to preview data:
-
Click OK to finish creating the data source.

Read Power BI data in PowerShell
Sometimes, you need to quickly access and work with your Power BI data in PowerShell. Whether you need a quick data overview or the complete dataset, this article will guide you through the process. Here are some common scenarios:
Viewing data in a terminal- Quickly peek at Power BI data
- Monitor data constantly in your console
- Export data to a CSV file so that it can be sliced and diced in Excel
- Export data to a JSON file so that it can ingested by other processes
- Export data to an HTML file for user-friendly view and easy sharing
- Create a schedule to make it an automatic process
- Store data internally for analysis or for further ETL processes
- Create a schedule to make it an automatic process
- Integrate data with other systems via external APIs
In this article, we will delve deeper into how to quickly view the data in PowerShell terminal and how to save it to a file. But let's stop talking and get started!
Reading individual fields
- Open your favorite PowerShell IDE (we are using Visual Studio Code).
-
Then simply follow these instructions:
"DSN=PowerBiDSN"
For your convenience, here is the whole PowerShell script:
# Configure connection string and query $connectionString = "DSN=PowerBiDSN" $query = "SELECT * FROM Customers" # Instantiate OdbcDataAdapter and DataTable $adapter = New-Object System.Data.Odbc.OdbcDataAdapter($query, $connectionString) $table = New-Object System.Data.DataTable # Fill the table with data $adapter.Fill($table) # Since we know we will be reading just 4 columns, let's define format for those 4 columns, each separated by a tab $format = "{0}`t{1}`t{2}`t{3}" # Display data in the console foreach ($row in $table.Rows) { # Construct line based on the format and individual Power BI fields $line = $format -f ($row["CustomerId"], $row["CompanyName"], $row["Country"], $row["Phone"]) Write-Host $line }
Access specific Power BI table field using this code snippet:
You will find more info on how to manipulate$field = $row["ColumnName"]
DataTable.Rows
property in Microsoft .NET reference.For demonstration purposes we are using sample tables which may not be available in Power BI. -
To read values in a console, save the script to a file and then execute this command inside PowerShell terminal:
You can also use even a simpler command inside the terminal, e.g.:
. 'C:\Users\john\Documents\dsn.ps1'
Retrieving all fields
However, there might be case, when you want to retrieve all columns of a query. Here is how you do it:
Again, for your convenience, here is the whole PowerShell script:
# Configure connection string and query
$connectionString = "DSN=PowerBiDSN"
$query = "SELECT CustomerId, CompanyName, Country, Phone FROM Customers"
# Instantiate OdbcDataAdapter and DataTable
$adapter = New-Object System.Data.Odbc.OdbcDataAdapter($query, $connectionString)
$table = New-Object System.Data.DataTable
# Fill the table with data
$adapter.Fill($table)
# Display data in the console
foreach ($row in $table.Rows) {
$line = ""
foreach ($column in $table.Columns) {
$value = $row[$column.ColumnName]
# Let's handle NULL values
if ($value -is [DBNull])
{
$value = "(NULL)"
}
$line += $value + "`t"
}
Write-Host $line
}
LIMIT
keyword in the query, e.g.:
SELECT * FROM Customers LIMIT 10
Using a full ODBC connection string
In the previous steps we used a very short format of ODBC connection string - a DSN. Yet sometimes you don't want a dependency on an ODBC data source (and an extra step). In those times, you can define a full connection string and skip creating an ODBC data source entirely. Let's see below how to accomplish that in the below steps:
-
Open ODBC data source configuration and click Copy settings:
ZappySys API Driver - Power BIConnect to your Power BI account and retrieve data, refresh datasets, etc.PowerBiDSN
- The window opens, telling us the connection string was successfully copied to the clipboard:
- Then just paste the connection string into your script:
- You are good to go! The script will execute the same way as using a DSN.
Have in mind that using a full connection string has length limitations.
Proceed to the next step to find out the details.
Limitations of using a full connection string
Despite using a full ODBC connection string may be very convenient it comes with a limitation: it's length is limited to 1024 symbols. It usually happens when API provider generates a very long Refresh Token when OAuth is at play. If it happens you use such API, you may get this error:
"Connection string exceeds maximum allowed length of 1024"
But there is a solution to this by storing the Refresh Token in a file instead of directly in ODBC connection string. Follow the steps below to achieve this.
- Open your ODBC data source
-
Hit Advanced tab and enter a file path:
ZappySys API Driver - Power BIConnect to your Power BI account and retrieve data, refresh datasets, etc.PowerBiDSNIf you cannot find the Advanced tab, try looking for Click to Configure link in Properties tab, under URL text box. Click it, and then configure the file path in OAuth Grant Options tab.
- Then click Copy settings button to copy a full connection string and paste it into your script.
- Proceed by pasting the connection string into your C# code as an argument when calling the OdbcConnection object's constructor.
- Before using it we still have to shorten it manually like this:
- Our troubles are over, now you should be able to execute the script with no problems.
Write Power BI data to a file in PowerShell
Save data to a CSV file
Export data to a CSV file so that it can be sliced and diced in Excel:
# Configure connection string and query
$connectionString = "DSN=PowerBiDSN"
$query = "SELECT * FROM Customers"
# Instantiate OdbcDataAdapter and DataTable
$adapter = New-Object System.Data.Odbc.OdbcDataAdapter($query, $connectionString)
$table = New-Object System.Data.DataTable
# Fill the table with data
$adapter.Fill($table)
# Export table data to a file
$table | ConvertTo-Csv -NoTypeInformation -Delimiter "`t" | Out-File "C:\Users\john\saved-data.csv" -Force
Save data to a JSON file
Export data to a JSON file so that it can ingested by other processes (use the above script, but change this part):
# Export table data to a file
$table | ConvertTo-Json | Out-File "C:\Users\john\saved-data.json" -Force
Save data to an HTML file
Export data to an HTML file for user-friendly view and easy sharing (use the above script, but change this part):
# Export table data to a file
$table | ConvertTo-Html | Out-File "C:\Users\john\saved-data.html" -Force
ConvertTo-Csv
, ConvertTo-Json
, and ConvertTo-Html
for other data manipulation scenarios.

Create Custom Stored Procedure in ZappySys Driver
You can create procedures to encapsulate custom logic and then only pass handful parameters rather than long SQL to execute your API call.
Steps to create Custom Stored Procedure in ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here
-
Go to Custom Objects Tab and Click on Add button and Select Add Procedure:
-
Enter the desired Procedure name and click on OK:
-
Select the created Stored Procedure and write the your desired stored procedure and Save it and it will create the custom stored procedure in the ZappySys Driver:
Here is an example stored procedure for ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here
CREATE PROCEDURE [usp_get_orders] @fromdate = '<<yyyy-MM-dd,FUN_TODAY>>' AS SELECT * FROM Orders where OrderDate >= '<@fromdate>';
-
That's it now go to Preview Tab and Execute your Stored Procedure using Exec Command. In this example it will extract the orders from the date 1996-01-01:
Exec usp_get_orders '1996-01-01';
-
Let's generate the SQL Server Query Code to make the API call using stored procedure. Go to Code Generator Tab, select language as SQL Server and click on Generate button the generate the code.
As we already created the linked server for this Data Source, in that you just need to copy the Select Query and need to use the linked server name which we have apply on the place of [MY_API_SERVICE] placeholder.
SELECT * FROM OPENQUERY([MY_API_SERVICE], 'EXEC usp_get_orders @fromdate=''1996-07-30''')
-
Now go to SQL served and execute that query and it will make the API call using stored procedure and provide you the response.
Create Custom Virtual Table in ZappySys Driver
ZappySys API Drivers support flexible Query language so you can override Default Properties you configured on Data Source such as URL, Body. This way you don't have to create multiple Data Sources if you like to read data from multiple EndPoints. However not every application support supplying custom SQL to driver so you can only select Table from list returned from driver.
If you're dealing with Microsoft Access and need to import data from an SQL query, it's important to note that Access doesn't allow direct import of SQL queries. Instead, you can create custom objects (Virtual Tables) to handle the import process.
Many applications like MS Access, Informatica Designer wont give you option to specify custom SQL when you import Objects. In such case Virtual Table is very useful. You can create many Virtual Tables on the same Data Source (e.g. If you have 50 URLs with slight variations you can create virtual tables with just URL as Parameter setting.
-
Go to Custom Objects Tab and Click on Add button and Select Add Table:
-
Enter the desired Table name and click on OK:
-
And it will open the New Query Window Click on Cancel to close that window and go to Custom Objects Tab.
-
Select the created table, Select Text Type AS SQL and write the your desired SQL Query and Save it and it will create the custom table in the ZappySys Driver:
Here is an example SQL query for ZappySys Driver. You can insert Placeholders also. Read more about placeholders here
SELECT "ShipCountry", "OrderID", "CustomerID", "EmployeeID", "OrderDate", "RequiredDate", "ShippedDate", "ShipVia", "Freight", "ShipName", "ShipAddress", "ShipCity", "ShipRegion", "ShipPostalCode" FROM "Orders" Where "ShipCountry"='USA'
-
That's it now go to Preview Tab and Execute your custom virtual table query. In this example it will extract the orders for the USA Shipping Country only:
SELECT * FROM "vt__usa_orders_only"
-
Let's generate the SQL Server Query Code to make the API call using stored procedure. Go to Code Generator Tab, select language as SQL Server and click on Generate button the generate the code.
As we already created the linked server for this Data Source, in that you just need to copy the Select Query and need to use the linked server name which we have apply on the place of [MY_API_SERVICE] placeholder.
SELECT * FROM OPENQUERY([MY_API_SERVICE], 'EXEC [usp_get_orders] ''1996-01-01''')
-
Now go to SQL served and execute that query and it will make the API call using stored procedure and provide you the response.

WITH (Url='/groups?$filter=contains(name,''MyWorkspace'') or name eq ''My Blue Workspace''',
Filter='$.value[*]')
/*
EXPLANATION:
- This configuration calls Power BI REST API "Get Groups" endpoint and gets the Workspaces back.
- This is achieved by "/groups" value in the "Url" parameter.
- Workspaces are filtered on the Power BI REST API side by using the "$filter" URL parameter.
- Only those Workspaces are returned that:
> contain a string value "MyWorkspace" or
> if the Workspace name is "My Blue Workspace" (each single quote is escaped with two single quotes).
- The SQL query parameter "Filter" uses JsonPath "$.value[*]".
- This gets JSON objects from "value" array and transforms them into SQL rows.
