How to Enable Custom Script in SharePoint Online Using PnP PowerShell?

Do you want to enable the custom script in SharePoint Online? In this tutorial, I will show you how to enable custom script in SharePoint Online using PnP PowerShell.

Why Enable Custom Script in SharePoint Online?

Let me show you, first of all, why we need to enable custom script in SharePoint Online.

In SharePoint Online modern sites, custom script is disabled by default because custom scripts can execute code with elevated permissions. Below are the things that are not possible when the custom script is disabled.

• The script editor web part and content editor web part are not available on the SharePoint Online site.
• Save list as template option will be disabled in the SharePoint Online list (Option will be hidden from the SharePoint list settings page)
• Files containing scripts will be disabled from uploading to the SharePoint site, etc.

To enable the custom script in a SharePoint Online site, you need to enable it in both places.

• Enable at the SharePoint Online admin center
• Enable at the SharePoint Online site level

Enable Custom Script in SharePoint Online Admin Center

Follow the below steps to enable custom scripts in the SharePoint Online admin center.

1. Open the classic SharePoint Online tenant settings page (https://<tenantname>-admin.sharepoint.com/_layouts/15/online/TenantSettings.aspx)
2. Alternatively, you can open the SharePoint Online admin center (E.g., https://szg52.sharepoint.com/), navigate to Settings, and click on the “classic settings page” link.
3. Here, navigate to the “Custom Script” section and choose the “Allow users to run custom script on self-service created sites” radio button like in the screenshot below:

Once this is done, you can enable the custom scripts at the SharePoint site level.

Enable Custom Script in SharePoint Online Site using PnP PowerShell

I will show you now how to enable custom script in SharePoint Online site using PnP PowerShell.

Below is the complete PowerShell script.

Connect-PnPOnline -Url "https://szg52.sharepoint.com/sites/PowerPlatformFAQs" -Interactive

# Enable Custom Script on the specified site
Set-PnPTenantSite -Identity $siteUrl -DenyAddAndCustomizePages:$false

# Verify Custom Script setting
$site = Get-PnPTenantSite -Identity $siteUrl
$site.DenyAddAndCustomizePages

To enable custom scripts on a specific site collection, you can use the Set-PnPTenantSite PnP PowerShell cmdlet. Here, you need to pass the parameter below:

-DenyAddAndCustomizePages:$false

After enabling custom scripts, you can verify that the setting has been applied correctly by running the following command:

$site = Get-PnPTenantSite -Identity $siteUrl
$site.DenyAddAndCustomizePages

I executed the above script using VS code, and you can see the output in the screenshot below:

This is how to enable the custom script in a SharePoint Online site using PnP PowerShell.

Set-PnPTenantSite -Identity $siteUrl -NoScriptSite:$false

# Verify Custom Script setting
$site = Get-PnPTenantSite -Identity $siteUrl
$site.NoScriptSite

Both methods should work fine.
