SharePoint Online: Bulk Create Dummy Files using PowerShell
Requirement: For a testing exercise, We had to bulk upload 5000+ documents to a document library in SharePoint Online.
PnP PowerShell to Create Dummy Files in Bulk in SharePoint Online
This PowerShell script bulk uploads the given file with unique names to the root folder of a specified SharePoint Online document library. Make sure you have the Local File “C:\Temp\Dummy.docx” and the SharePoint document library already before running this script.
#Parameters
$SiteURL = "https://crescent.sharepoint.com/sites/Dev"
$LibraryName = "LargeLibrary"
$LocalFile= "C:\Temp\Dummy.docx"
$MaxFilesCount = 5000
Try {
#Get the File
$File = Get-ChildItem $LocalFile
#Connect to PnP Online
Connect-PnPOnline -Url $SiteURL -Interactive
#$Library = Get-PnPList -Identity $LibraryName
$FileCounter = 1
While($FileCounter -le $MaxFilesCount)
{
$NewFileName= $File.BaseName+"_"+$FileCounter+".docx"
Try
{
Add-PnPFile -Path $File -Folder $LibraryName -NewFileName $NewFileName | Out-Null
}
Catch
{
Write-host "Error: $($_.Exception.Message)" -foregroundcolor Red
}
Write-host -f Green "New File '$NewFileName' Created ($FileCounter of $MaxFilesCount)!"
$FileCounter++
}
}
Catch {
write-host -f Red "Error Uploading File:"$_.Exception.Message
}
Based on the number of files and file size, the script’s execution time varies and creates documents on the given document library.
Similarly, to bulk create a large number of list items in SharePoint Online, use: PowerShell to Bulk Add List Items in SharePoint Online using PnP-Batch
