Salesforce Connector for PowerShell

In this article you will learn how to integrate Salesforce data in PowerShell without coding in just a few clicks (live / bi-directional connection to Salesforce). Salesforce Connector can be used to extract/load large amount of data from/in Salesforce.com without any programming. You can use simple Table mode or Query mode with full SOQL query language support (SOQL=Salesforce.com Object Query Language)..

Using Salesforce 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.

Create ODBC Data Source (DSN) based on ZappySys Salesforce Driver

Step-by-step instructions

To get data from Salesforce using PowerShell we first need to create a DSN (Data Source) which will access data from Salesforce. We will later be able to read data using PowerShell. Perform these steps:

  1. Install ZappySys ODBC PowerPack.

  2. Open ODBC Data Sources (x64):
    Open ODBC Data Source

  3. Create a User Data Source (User DSN) based on ZappySys Salesforce Driver

    ZappySys Salesforce Driver
    Create new User DSN for ZappySys Salesforce Driver
    You 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.
  4. Now, we need SalesForce Connection. Lets create it. ODBC SalesForce Driver - Create Connection

  5. Now, When you see DSN Config Editor with zappysys logo first thing you need to do is change default DSN Name at the top and Click on Preview Tab, Select Table from Tables Dropdown or you can enter or modify a SOQL query and click on Preview Data.
    This example shows how to write simple SOQL query (Salesforce Object Query Language). It uses WHERE clause. For more SOQL Queries click here.
    SOQL is similar to database SQL query language but much simpler and many features you use in database query may not be supported in SOQL (Such as JOIN clause not supported). But you can use following Queries for Insert, Update, Delete and Upsert(Update or Insert record if not found).

    SELECT * FROM Account WHERE Name like '%Oil%'

  6. Click OK to finish creating the data source

Read Salesforce data in PowerShell

Sometimes, you need to quickly access and work with your Salesforce 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 Salesforce data
  • Monitor data constantly in your console
Saving data to a file
  • 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
Saving data to a database
  • Store data internally for analysis or for further ETL processes
  • Create a schedule to make it an automatic process
Sending data to another API
  • 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

  1. Open your favorite PowerShell IDE (we are using Visual Studio Code).
  2. Then simply follow these instructions:
    "DSN=SalesforceDSN"
    Read API data with PowerShell using ODBC DSN in Visual Code

    For your convenience, here is the whole PowerShell script:

    # Configure connection string and query
    $connectionString = "DSN=SalesforceDSN"
    $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 Salesforce fields
        $line = $format -f ($row["CustomerId"], $row["CompanyName"], $row["Country"], $row["Phone"])
        Write-Host $line
    }
    
    Access specific Salesforce table field using this code snippet:
    $field = $row["ColumnName"]
    You will find more info on how to manipulate DataTable.Rows property in Microsoft .NET reference.
    For demonstration purposes we are using sample tables which may not be available in Salesforce.
  3. To read values in a console, save the script to a file and then execute this command inside PowerShell terminal: Read API data in PowerShell using ODBC DSN
    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:

"DSN=SalesforceDSN"
Read all API columns from ODBC data source in PowerShell

Again, for your convenience, here is the whole PowerShell script:

# Configure connection string and query
$connectionString = "DSN=SalesforceDSN"
$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
}
You can limit the numbers of lines to retrieve by using a 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:

  1. Open ODBC data source configuration and click Copy settings:
    ZappySys Salesforce Driver - Salesforce
    Salesforce Connector can be used to extract/load large amount of data from/in Salesforce.com without any programming. You can use simple Table mode or Query mode with full SOQL query language support (SOQL=Salesforce.com Object Query Language).
    SalesforceDSN
    Copy ODBC connection string to use in PowerShell
  2. The window opens, telling us the connection string was successfully copied to the clipboard: Successful ODBC connection string copying
  3. Then just paste the connection string into your script: Paste ODBC connection string in PowerShell to read API data
  4. 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.

  1. Open your ODBC data source
  2. Hit Advanced tab and enter a file path:
    ZappySys Salesforce Driver - Salesforce
    Salesforce Connector can be used to extract/load large amount of data from/in Salesforce.com without any programming. You can use simple Table mode or Query mode with full SOQL query language support (SOQL=Salesforce.com Object Query Language).
    SalesforceDSN
    Configure Refresh Token in ODBC data source

    If 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.

  3. Then click Copy settings button to copy a full connection string and paste it into your script.
  4. Before using it we still have to shorten it manually like this: Shorten ODBC connection string to read API data in PowerShell
  5. Our troubles are over, now you should be able to execute the script with no problems.

Write Salesforce 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=SalesforceDSN"
$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
Check useful PowerShell cmdlets other than ConvertTo-Csv, ConvertTo-Json, and ConvertTo-Html for other data manipulation scenarios.
