CSV Microsoft Graph connector

The CSV Microsoft Graph connector allows your organization to ingest content from CSV files stored in SharePoint libraries and Azure Data Lake Storage (ADLS). After you configure the connector and index content from these sources, end users can find CSV files in Microsoft Search and Microsoft 365 Copilot.

This article is for anyone who configures, runs, and monitors a CSV Microsoft Graph connector. It supplements the general setup process and shows instructions that apply only to this connector.

Before you get started

• Make sure there's no whitespace in the CSV headers

• For a SharePoint data source, you can authenticate using either of the two OAuth providers: Microsoft Entra ID (coming soon) or SharePoint provider (retiring soon).

  • For authenticating using Microsoft Entra ID you'll need to create and register an app on Microsoft Entra ID.
  • For authenticating using SharePoint provider you'll need to create a SharePoint app with OAuth configuration.

Tip

You will be able to switch the OAuth provider for your published connection from SharePoint to Microsoft Entra ID, once available

• For an ADLS data source, you'll need to create an ADLS storage account.

SharePoint data source

Upload your CSV files

Verify the .csv files you want to index have been uploaded to a SharePoint document library. You can use an existing SharePoint site or create a new one.

Create an app on Microsoft Entra ID

1. Go to the Azure portal and sign in with admin credentials for the tenant.

2. Navigate to Microsoft Entra ID -> Manage -> App registrations from the navigation pane and select New registration.

3. Provide a name for the app and select Register.

4. Make a note of the application (client) ID.

5. Open API permissions from the navigation pane and select Add a permission.

6. Select SharePoint and then Delegated permissions.

7. Search for the following permissions and select Add permissions.
   a. AllSites.Read
   b. User.Read.All

8. Select Grant admin consent for [TenantName] and confirm by selecting Yes.

9. Check that the permissions are in the "granted" state.

10. Open Authentication from the navigation pane and select Add a platform. Select Web under Web applications and add the following under Redirect URIs (Authorization callback URIs):

    • For M365 Enterprise: https://gcs.office.com/v1.0/admin/oauth/callback
    • For M365 Government: https://gcsgcc.office.com/v1.0/admin/oauth/callback

Configuring the client secret for authentication

1. Go to the Azure portal and sign in with admin credentials for the tenant.

2. Open App Registration from the navigation pane and go to the appropriate App. Under Manage, select Certificates and Secrets.

3. Select New Client Secret and select an expiry period for the secret. Copy the generated secret and save it because it is not shown again.

4. Use this Client secret and the application ID to configure the connector.

Create a SharePoint app with OAuth configuration (retiring soon)

1. Go to https://Org-Name.sharepoint.com/sites/mysite/_layouts/15/appregnew.aspx.
2. On the Client ID and Client Secret fields, select Generate.
3. For Title, enter an app name.
4. In the App Domain field, enter www.gcs.com.
5. In the Redirect URL field, enter https://www.gcs.com.
6. Select Create.
7. Copy the app configuration information, including the Client ID and Client Secret. You'll need it when you set up the CSV connector.

Enable app permissions to allow customAppAuthentication

In PowerShell (SharePoint Online Management Shell), run these commands in administrative mode. Use the email address of the admin configuring the connector and your organization name. When the password pop-up appears, the admin should enter their password.

Install-Module -Name Microsoft.Online.SharePoint.PowerShell
$adminUPN=”<admin@contoso.onmicrosoft.com>”
$orgName=“<contoso>”
$userCredential = Get-Credential -UserName $adminUPN -Message "Enter your password."
Connect-SPOService -Url https://$orgName-admin.sharepoint.com -Credential $userCredential
Set-spotenant –DisableCustomAppAuthentication $false

Note

If you're using PowerShell 7, use this command first Import-Module microsoft.online.sharepoint.powershell -UseWindowsPowerShell

Note

If you're using multifactor authentication, use Connect-SPOService -Url https://$orgName-admin.sharepoint.com.

Complete the app configuration

1. Go to https://Org-Name.sharepoint.com/sites/mysite/_layouts/15/appinv.aspx.
2. In the App ID field, paste the client ID of the SharePoint app and select Lookup.
3. In the permission Request XML field, paste this code and select Create.

<AppPermissionRequests AllowAppOnlyPolicy="true">
    <AppPermissionRequest Scope="http://sharepoint/content/sitecollection/web" Right="Read" />
</AppPermissionRequests>

4. Select Trust it.

ADLS data source

Create an ADLS storage account

For step-by-step guidance, see Create a storage account. To allow file storage capabilities, on the Advanced tab, select Enable hierarchical namespace and Create a container for this site.

When you set up the CSV Microsoft Graph connector, you'll need to provide a primary storage connection string. To find it, open the storage account you created and select Access keys. Select Show keys and copy the connection string for Key1.

Step 1: Add a Microsoft Graph connector in the Microsoft 365 admin center

Add CSV Microsoft Graph connector

Follow the general setup instructions.

Step 2: Name the connection

Follow the general setup instructions.

Step 3: Configure connection settings

The data source settings are different for SharePoint and ADLS.

Note

Ensure that your csv file does not have any formatting or spaces (‘ ‘) present in header rows.

For a SharePoint source

1. In the Data Source settings, select SharePoint as your datasource.

2. In SharePoint site, enter the site URL, https://Org-Name.sharepoint.com/Site-Name, for example.

3. In Document Library, enter the name of the library where the .csv files are stored.

4. In OAuth provider, you can either select SharePoint Provider (retiring soon) or Microsoft Entra ID
   

   a. For Microsoft Entra ID (coming soon):
   1. Authentication Type, select Oauth2.0(authorization code).
   2. Enter the Client ID and Client Secret you copied when you created the Microsoft Entra ID app.
   3. Select Sign In. You should get a Connection successful message.
   

   b. For SharePoint Provider (retiring soon):
   1. In Authentication Type, select Oauth2.0(client credentials).
   2. Enter the Client ID and Client Secret you copied when you created the SharePoint app.
   3. Select Test Connection. You should get a Connection successful message.

To control access on a file level, enter Microsoft Entra users or groups.

For an ADLS source

1. In the Data Source settings, select Azure Data Lake Storage(ADLS) as your datasource.
2. In Primary storage connection string, enter the connection string you copied.
3. Enter the Container name and Filename.
4. Select Test Connection. You should get a The connection is successful message.

Note

If your datasource contains multiple .csv files with the same headers, select include all CSV files in location.

To control access on a file level, enter Microsoft Entra users or groups.

Step 4: Multi-items delimiter (Optional)

If your source columns can take multiple values, enter a multi-item delimiter, a semicolon (;) for example.

Step 5: Parsed properties settings

This page returns the first row from your .csv file as Source Properties. To modify the datatype, in the Unique identifier list select at least one option.

To control access on an item level, select columns mapped to allowed users and allowed groups. You should include two columns, AllowedUsers and AllowedGroups, in the .csv file. Each row should contain the Microsoft Entra IDs.

Note

The CSV Microsoft Graph connector supports file- or item-level access control. If both are enabled, only the file-level access control is applied.

Step 6: Assign property labels

Follow the general setup instructions.

Note

IconURL label is populated by default and the mapping cannot be changed.

Step 7: Manage schema

Follow the general setup instructions.

Step 8: Manage search permissions

• For file- or item-level access control, select Only people with access to this data source.
• Selecting Everyone allows everyone in your organization to see search results from this data source.

Step 9: Choose refresh settings

Follow the general setup instructions.

Step 10: Review connection

Follow the general setup instructions.
