SharePoint Online: Save List as Template Missing? Here is how to enable it!

Problem: “Save List as Template” is missing in SharePoint Online modern sites!

Root Cause: We don’t get the “Save list as Template” link on the list settings page in sites with custom script disabled. To enable the save list as a template in SharePoint Online, we should enable the custom script for a site!

Solution:

Enable Custom Scripting at SharePoint Admin Center and Site Collection Levels!

How to Enable Custom Script in SharePoint Online?

To allow custom script in SharePoint Online, follow these steps:

• Sign in to Office 365 and go to the SharePoint Online Admin Center.
• Click on Settings from the left navigation >> Scroll down to “Custom Script” section
• Under Custom Script section, Set “Allow users to run custom script on personal site” and “Allow
  users to run custom script on self-service created sites” options. 

  

• Click on “OK” to save your changes.

This enables custom scripts in SharePoint Online. However, this change may take up to 24 hours to reflect. To enable scripting on a particular site collection immediately, use this PowerShell script through SharePoint Online Management Shell.

Enable Custom Scripting at Site Collection Level:

Let’s use PowerShell to fix the save list as template missing in the SharePoint Online issue.

#Variables for Admin Center and Site Collection URL
$AdminCenterURL = "https://crescent-admin.sharepoint.com/"
$SiteURL="https://crescent.sharepoint.com/Sites/marketing"

#Connect to SharePoint Online
Connect-SPOService -url $AdminCenterURL -Credential (Get-Credential)

#Disable DenyAddAndCustomizePages Flag
Set-SPOSite $SiteURL -DenyAddAndCustomizePages $False
