PowerShell cmdlet New-SPSite is used to create new site collections in SharePoint. It takes URL and Owner mandatory parameters with other parameters. Here is an example:

Create SharePoint Site Collection Using PowerShell :

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue

#Parameters to create new site collection
$SiteName = "Demo"
$SiteURL= "http://intranet.Crescent.com/sites/demo"
$SiteOwner = "Crescent\SPAdmin"
$SiteTemplate = "STS#0"
 
#create site collection with given parameters
New-SPSite -Url $URL -Name $SiteName -OwnerAlias $SiteOwner -Template $SiteTemplate

PowerShell to Create Multiple Site Collections in Bulk from a CSV File:

Let’s add some error handling and wrap New-SPSite into a reusable PowerShell function, to create multiple site collections from a CSV file.

  • Step 1: Create a CSV file in the below format. Populate the column values according to your requirements.
    create site collections from csv in sharepoint
  • Step 2: Use this PowerShell script to read from CSV and create site collections in bulk. 
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
 
#Function to Create new Site Collection
Function Create-SPSite
{
  param
    (
        [string]$Name  = $(throw "Please Provide the Site Name!"),
        [string]$URL = $(throw "Please Provide the Site URL!"),
        [string]$Owner = $(throw "Please Provide the Site Owner!"),
        [string]$Template = $(throw "Please Provide the Site Template!")
    )
Try {
   #Set the Error Action
    $ErrorActionPreference = "Stop"
 
    #Check if the site collection exists already
    $SiteExists = Get-SPSite | where {$_.url -eq $URL}
    #Check if site exists in the recycle bin
    $SiteExistsInRecycleBin = Get-SPDeletedSite | where {$_.url -eq $URL}
  
    If($SiteExists -ne $null)
    {
        write-host "Site $($url) exists already!" -foregroundcolor red
    }
    elseIf($SiteExistsInRecycleBin -ne $null)
    {
        write-host "Site $($url) exists in the recycle bin!" -foregroundcolor red
    }
    else
    {
        #create site collection
        New-SPSite -Url $URL -Name $Name -OwnerAlias $Owner -Template $Template
        write-host "Site Collection $($url) Created Successfully!" -foregroundcolor Green
    }
}
catch {
    write-host "Error: $($_.Exception.Message)" -foregroundcolor Red
    }
Finally {
    #Reset the Error Action to Default
    $ErrorActionPreference = "Continue"
 } 
}
 
#Read from CSV and create site collection
Import-Csv "C:\SitesToCreate.csv" | Foreach-Object { 
   Create-SPSite -Name $_.SiteName -URL $_.SiteURL -Owner $_.SiteOwner -Template $_.SiteTemplate  }

This script uses the combination of Import-Csv and SharePoint cmdlet to create multiple site collections in SharePoint. There are other parameters such as Content Database, Language, Site description, etc you can incorporate with this.

  • Error: Cannot bind argument to parameter ‘Url’ because it is an empty string.

    • That means, The URL parameter you passed to the function is null! Just make sure your CSV file has exactly the same column names and has valid URLs in it!
