Delete custom SharePoint site designs

Summary

Site designs and especially site scripts can be something that ends up just hanging around in your tenant for a long time even though you no longer need them for anything. Use the scripts below to get rid of them. You might also find some site scripts that are not linked to any site design and hence never get executed!

Warning

Please be aware this script contains a command that will remove or delete an artifact, ensure you test and understand the implications of running the script.

Connect-SPOService "https://contoso-admin.sharepoint.com"

$keepThese = "Register the new site", "Corporate Basic Site", "Corporate Internal Site"
$siteDesigns = Get-SPOSiteDesign
$siteDesigns = $siteDesigns | Where-Object { -not ($keepThese -contains $_.Title)}

if ($siteDesigns.Count -eq 0) { break }

$siteDesigns | Format-Table Title, SiteScriptIds, Description
Read-Host -Prompt "Press Enter to start deleting (CTRL + C to exit)"
$progress = 0
$total = $siteDesigns.Count

foreach ($siteDesign in $siteDesigns)
{
  $progress++
  Write-Host $progress / $total":" $siteDesign.Title
  Remove-SPOSiteDesign $siteDesign.Id
}
