Here is a script I wrote to bulk upload files and metadata into SharePoint. To make this work you need two things, a CSV file containing the names of the files to upload and the metadata associated with the item.

In this example, the CSV file has the following format:

• filename,cust_number,document_type

The script reads the CSV file, creates a folder in the document library named with the value of the “cust_number” field, and then uploads the file “filename” and populates the “document_type” column.

The WebClient command is used to upload the file into the document library. The script also checks the item in (if required).

Write-Progress -Activity “Connecting to SharePoint Site,” -Status “Please wait …”
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue

$CSVFile = “C:\FilesToImport\filelist.csv”

$SPWebURL = “http://sharepoint/site”
$SPListURL = “http://sharepoint/site/library/”
$BaseFolder = “C:\FilesToImport\Files”
$Credentials = [System.Net.CredentialCache]::DefaultCredentials

$SPWebObject = Get-SPWeb $SPWebURL
write-host $SPListURL
$SPListObject = $SPWebObject.GetListFromUrl(“library/Forms/AllItems.aspx”)
$WebClient = New-Object System.Net.WebClient
$WebClient.Credentials = $Credentials

Write-Progress -Activity “Importing CSV File,” -Status “Please wait …”

$CSVObject = Import-CSV $CSVFile
$Index = 0
$Max = $CSVObject.Count

ForEach($CSVItem in $CSVObject)
{
$Index++
Write-Progress -Activity “Updating Metadata” -Status “Processing Item $Index of $Max”

$FileName = $CSVItem.File_name + “.pdf”
$ID_Number = $CSVItem.Cust_Number
$DocumentType = $CSVItem.Document_Type

$FullFileName = $BaseFolder + “\” + $FileName
write-host $FullFileName
if (Test-Path ($FullFileName))
{
$UploadPath = $SPListUrl + “/” + $Cust_Number + “/” + $FileName
$WebClient.UploadFile($UploadPath, “PUT”, $FullFileName)$SPListItemsObject = $SPListObject.Items | where {$_[‘Name’] -eq $FileName}
ForEach($SPListItem in $SPListItemsObject)
{
$SPListItem[‘Document_Type’] = $DocumentType

$SPListItem.Update()
if ($SPListItem.file.CheckOutStatus -ne “None”)
{
$SPListItem.file.CheckIn(“”)
}
}
}
else
{
Add-Content ErrorLog.txt $FullFileName
}
}

I’ve used this script in a few scenarios. I hope you find it useful too.
