Sometimes we have a business requirement to get site collections with all the sub-webs so we can achieve the solution easily using PnP PowerShell. Let’s see step-by-step implementation:

Implementation

Open Windows PowerShell ISE
Create a new file and write a script

Now we will see all the steps which we required to achieve the solution:

We will initialize the admin site URL, username, and password in the global variables.
Then we will create a Login function to connect the O365 SharePoint Admin site.
Create a function to get all site collections and all the sub-webs So in the end, our script will be like this,

$SiteURL = "https://domain-admin.sharepoint.com/"
$UserName = "UserName@domain.onmicrosoft.com"
$Password = "********"
$SecureStringPwd = $Password | ConvertTo-SecureString -AsPlainText -Force 
$Creds = New-Object System.Management.Automation.PSCredential -ArgumentList $UserName, $SecureStringPwd

Function Login {
    [cmdletbinding()]
    param([parameter(Mandatory = $true, ValueFromPipeline = $true)] $Creds)
    Write-Host "Connecting to Tenant Admin Site '$($SiteURL)'" 
    Connect-PnPOnline -Url $SiteURL -Credentials $creds
    Write-Host "Connection Successfull"
}

Function AllSiteCollAndSubWebs() {
    Login($Creds)
    $TenantSites = (Get-PnPTenantSite) | Select Title, Url       
       
    ForEach ( $TenantSite in $TenantSites) { 
        Connect-PnPOnline -Url $TenantSite.Url -Credentials $Creds
        Write-Host $TenantSite.Title $TenantSite.Url
        $subwebs = Get-PnPSubWebs -Recurse | Select Title, Url
        foreach ($subweb in $subwebs) { 
            Connect-PNPonline -Url $subweb.Url -Credentials $Creds
            Write-Host $subweb.Title $subweb.Url 
        }  
    }
}
