Powershell mail merge

PowerShell provides several ways to perform mail merge operations. Here are a few examples:

Using the Microsoft.Office.Interop namespace

You can use the Microsoft.Office.Interop namespace to interact with Microsoft Office applications, including Word. Here's an example of how you can use it to perform a mail merge:

# Add the Microsoft.Office.Interop namespace
Add-Type -AssemblyName Microsoft.Office.Interop

# Create a new Word application object
$word = New-Object -ComObject Word.Application

# Open the template document
$template = $word.Documents.Open("C:\Path\To\Template.docx")

# Set the data source
$dataSource = @(
    [PSCustomObject]@{
        Name = "John Doe"
        Email = "[email protected]"
    }
    [PSCustomObject]@{
        Name = "Jane Doe"
        Email = "[email protected]"
    }
)

# Perform the mail merge
$template.MailMerge.OpenDataSource("C:\Path\To\Data.csv", 1)
$template.MailMerge.Destination = 1
$template.MailMerge.Execute()

# Save the merged document
$template.SaveAs("C:\Path\To\MergedDocument.docx")

# Close the Word application
$word.Quit()

Using the Word.Application object

You can also use the Word.Application object to perform a mail merge. Here's an example:

# Create a new Word application object
$word = New-Object -ComObject Word.Application

# Open the template document
$template = $word.Documents.Open("C:\Path\To\Template.docx")

# Set the data source
$dataSource = @(
    [PSCustomObject]@{
        Name = "John Doe"
        Email = "[email protected]"
    }
    [PSCustomObject]@{
        Name = "Jane Doe"
        Email = "[email protected]"
    }
)

# Perform the mail merge
$template.MailMerge.OpenDataSource($dataSource, 1)
$template.MailMerge.Destination = 1
$template.MailMerge.Execute()

# Save the merged document
$template.SaveAs("C:\Path\To\MergedDocument.docx")

# Close the Word application
$word.Quit()

Using a third-party library

There are also third-party libraries available that provide mail merge functionality in PowerShell. One example is the MailMerge module, which can be installed using the following command:

Install-Module -Name MailMerge

Here's an example of how you can use the MailMerge module to perform a mail merge:

# Import the MailMerge module
Import-Module -Name MailMerge

# Set the data source
$dataSource = @(
    [PSCustomObject]@{
        Name = "John Doe"
        Email = "[email protected]"
    }
    [PSCustomObject]@{
        Name = "Jane Doe"
        Email = "[email protected]"
    }
)

# Set the template document
$template = "C:\Path\To\Template.docx"

# Perform the mail merge
MailMerge -Template $template -DataSource $dataSource -OutputPath "C:\Path\To\MergedDocument.docx"

Note that the MailMerge module requires Microsoft Office to be installed on the system.
