SharePoint PowerShell: Upload multiple documents to sharepoint document library

Hi,

I was creating a script to replicate document library structure similar to Prod just in order to test the ShareGate Migration. Let me take a brief description about my scenario:

Description:

There is a document library present on Prod, which contains bulk document (~3000). Now I need to update metadata for all those documents using Excel sheet and ShareGate. I don't have access to the Production library and not even replicate the Library to my Dev environment as it contains some very confidential documents.

Solution:

I have decided to create a script which will take one template document from file system and read name of document from one of columns of excel. The script will take some time(~hours in case of thousand documents) to upload the template with the new file name. The inputs to the script will be

1. Path of the excel which contains name of documents in one column


2. Path of the file where the template is placed on file system


3. Url of the sharepoint web site


4. Name of the document library

Code: 

# Add SharePoint Snapin to PowerShell            
if((Get-PSSnapin | Where {$_.Name -eq "Microsoft.SharePoint.PowerShell"}) -eq $null)             
{            
 Add-PSSnapin Microsoft.SharePoint.PowerShell            
}
$exlFile = "D:\Work\Book2 - Copy.xlsx"
$fileExt = ".pdf"
#$filePath =  "D:\Work\IAEA.docx"  
$filePath = "D:\Work\pdf.pdf"
$webUrl = "http://server/sites/site"            
$docLibName = "Library Name"      

try {    
    $xl = New-Object -COM "Excel.Application"
    #$xl.Visible = $true
    $wb = $xl.Workbooks.Open($exlFile)
    #$ws = $wb.Sheets.Item('Log')
    $ws = $wb.Sheets.Item('Sheet1')
    $lines = $ws.UsedRange.Rows.Count

    $spWeb = Get-SPWeb -Identity $webUrl             
    $spWeb.AllowUnsafeUpdates = $true;            
    $lib = $spWeb.Lists[$docLibName]            
    $folder = $lib.RootFolder            
    #$sourceFileName = $filePath.Substring($filePath.LastIndexOf("\")+1)             
    $file= Get-ChildItem $filePath  
    
    $docLibraryUrl = $lib.RootFolder.ServerRelativeUrl
    $uploadfolder = $spWeb.getfolder($docLibraryUrl + $folderPathWithinDocLibrary)
            
    $fileStream = ([System.IO.FileInfo] (Get-Item $file.FullName)).OpenRead()     

    for ($line = 2; $line -le $lines; $line ++) {       
        $fileName = $ws.Columns.Item(1).Rows.Item($line).Text
        
        if($fileName -ne "")
        {
            $fileName
            #Check if File exist
            $item = $uploadfolder.Files | where{$_.Name -eq $fileName}
            if(!$item)
            {                
                #Add file            
                write-host -NoNewLine -f yellow "Addin file " $fileName " to " $folder.ServerRelativeUrl "..."                    
                $newFilePath = $docLibraryUrl + $folderPathWithinDocLibrary + "/" + $fileName
                write-host "Creating document: $newFilePath ..."
                $spFile = $uploadfolder.Files.Add($newFilePath, [System.IO.Stream]$fileStream, $true)  
                
                write-host -f Green "...Success!" 
            }
        }
    }
     #Close file stream            
    $fileStream.Close()
    $spWeb.AllowUnsafeUpdates = $false;
    $spWeb.Dispose();
    $xl.Quit()
}
finally { 
    $wb.Close()
    $xl.Quit()
    [System.Runtime.Interopservices.Marshal]::ReleaseComObject($xl)
}

Output:



Hope that code help you finding solution.

Happy SharePointing :)
