Create Azure AD groups from a CSV file

To create Azure AD groups from a CSV file, you can use Microsoft Graph API and the Azure AD Graph API to programmatically create groups in your Azure Active Directory tenant. Here are the steps to follow:

1. Authenticate to Azure AD: You need to authenticate to Azure AD by acquiring a token using OAuth 2.0.
2. Read the CSV file: Read the CSV file containing the group information into your code.
3. Create the groups: Use the Microsoft Graph API or the Azure AD Graph API to create the groups in your Azure AD tenant. The API requires you to send an HTTP request to create a group, which includes the group name and other properties such as description and mailNickname.
4. Import the members: You can also import the members of each group from the CSV file by sending an HTTP request to add members to a group.

Note: To avoid making multiple API calls for each group, you can also batch multiple group creation and member addition requests in a single API call, if supported by the API you are using.

Here's an example of how to create Azure AD groups from a CSV file using Microsoft Graph API in PowerShell:

# Load the CSV file into memory
$Groups = Import-Csv -Path <Path to the CSV file>

# Authenticate to Azure AD
Connect-AzureAD

# Loop through each row in the CSV file and create a group
foreach ($Group in $Groups) {
    $group = New-Object -TypeName Microsoft.Graph.Group
    $group.DisplayName = $Group.DisplayName
    $group.MailNickname = $Group.MailNickname
    $group.Description = $Group.Description

    # Create the group
    $createdGroup = Invoke-AzureADGraphRequest -HttpMethod Post -ApiVersion "beta" -Path "/groups" -Body $group

    # Add members to the group
    foreach ($Member in $Group.Members) {
        $member = New-Object -TypeName Microsoft.Graph.DirectoryObject
        $member.Id = $Member

        Invoke-AzureADGraphRequest -HttpMethod Post -ApiVersion "beta" -Path "/groups/$($createdGroup.Id)/members/$ref" -Body $member
    }
}
