SharePoint Online: PowerShell to Bulk Create Folders in a Document Library from a CSV File

Requirement: Create Multiple Folders in a Document Library from a CSV File in SharePoint Online.

PowerShell to Bulk Create Folders from a CSV File in SharePoint Online:

Are you looking to create multiple folders in SharePoint Online but don’t want to have to do it one at a time? Maybe you want to create a folder structure for a new project or sort your documents into different categories. This article will show you how to use PowerShell to create multiple folders quickly.

I got to create a bunch of folders in a SharePoint Online document library! This PowerShell script takes folder names from a CSV file and creates folders in the specified document library.

#Config Variables
$SiteURL = "https://crescent.sharepoint.com/sites/Ops"
$CSVFilePath = "C:\Temp\Folders.csv"
$LibraryName = "Documents"

Try {
    #Connect to PnP Online
    Connect-PnPOnline -Url $SiteURL -Interactive
    $Web = Get-PnPWeb

    #Get the Document Library and its site relative URL
    $Library = Get-PnPList -Identity $LibraryName -Includes RootFolder
    If($Web.ServerRelativeUrl -eq "/")
    {
        $LibrarySiteRelativeURL = $Library.RootFolder.ServerRelativeUrl
    }
    else
    {
        $LibrarySiteRelativeURL = $Library.RootFolder.ServerRelativeUrl.Replace($Web.ServerRelativeUrl,'')
    }

    #Get the CSV file
    $CSVFile = Import-Csv $CSVFilePath
 
    #Read CSV file and create folders
    ForEach($Row in $CSVFile)
    {
        #Replace Invalid Characters from Folder Name, If any
        $FolderName = $Row.FolderName
        $FolderName = [RegEx]::Replace($FolderName, "[{0}]" -f ([RegEx]::Escape([String]'\"*:<>?/\|')), '_')

        #Frame the Folder Name
        $FolderURL = $LibrarySiteRelativeURL+"/"+$FolderName

        #Create Folder if it doesn't exist
        Resolve-PnPFolder -SiteRelativePath $FolderURL | Out-Null
        Write-host "Ensured Folder:"$FolderName -f Green
    }
}
catch {
    write-host "Error: $($_.Exception.Message)" -foregroundcolor Red
}

This will save you a lot of time and ensure a more consistent folder structure across your site. Here is my CSV File format:

How about creating folders and sub-folders in multiple document libraries? Here is my CSV format:

#Config Variables
$SiteURL = "https://crescent.sharepoint.com/sites/marketing"
$CSVFilePath = "C:\Temp\Folders.csv"
 
Try {
    #Connect to PnP Online
    Connect-PnPOnline -Url $SiteURL -Interactive

    #Get the CSV file
    $CSVFile = Import-Csv $CSVFilePath
  
    #Read CSV file and create folders
    ForEach($Row in $CSVFile)
    { 
        #Create Folder if it doesn't exist
        Resolve-PnPFolder -SiteRelativePath $Row.FolderSiteRelativeURL | Out-Null
        Write-host "Ensured Folder:"$Row.FolderSiteRelativeURL -f Green
    }
}
catch {
    write-host "Error: $($_.Exception.Message)" -foregroundcolor Red
}

  • Hi

    I’m trying to create a folder across multiple (51) document libraries. I would like to use a CSV file to feed in the document library and folder location. Would this be possible with the above script/procedure? If so, what alterations should I make?

    Hope you can help.

  • Anyone have any way to add folders, but at the same time ‘remove inherited permissions’ so each created folder does not use parent folder permissions?

  • I got the following error:

    Write-host “Ensured Folder:”$Row.FolderSiteRelativeURL -f Green
    | ~~~~~~~
    | Unexpected token ‘Ensured’ in expression or statement.

  • Thanks for sharing your knowledge, the script was executed but no folder was created and I received warning message “Consider using -Interactive instead, which provides better functionality.

  • I was getting the same result until I added FolderSiteRelativeURL as the first row of my CSV file.

    Now I am getting the following if anyone can help with that.
    Access denied. You do not have permission to perform this action or access this resource.

  • Error: Cannot bind argument to parameter ‘SiteRelativePath’ because it is null.

    Why is that happening?

    #Config Variables
    $SiteURL = “https://crescent.sharepoint.com/sites/marketing”
    $CSVFilePath = “C:TempFolders.csv”

    Try {
    #Connect to PnP Online
    Connect-PnPOnline -Url $SiteURL -Interactive

    #Get the CSV file
    $CSVFile = Import-Csv $CSVFilePath

    #Read CSV file and create document document library
    ForEach($Row in $CSVFile)
    {
    #Create Folder if it doesn’t exist
    Resolve-PnPFolder -SiteRelativePath $Row.FolderSiteRelativeURL | Out-Null
    Write-host “Ensured Folder:”$Row.FolderSiteRelativeURL -f Green
    }
    }
    catch {
    write-host “Error: $($_.Exception.Message)” -foregroundcolor Red
    }
