PowerShell Script to upload file to SharePoint

$localFilePath = "D:\Annual Report\report-2023.xlsx"

if (-not (Get-Module -Name SharePointPnPPowerShellOnline -ListAvailable)) {
    Install-Module SharePointPnPPowerShellOnline -Force
}

$siteUrl = "https://your-tenant-name.sharepoint.com/sites/your-site-name"
Connect-PnPOnline -Url $siteUrl

$destinationLibrary = "Shared Documents"

Add-PnPFile -Path $localFilePath -Folder $destinationLibrary -NewFileName "report-2023.xlsx"
