Function Export-SPRListItem { <# .SYNOPSIS Exports all items from a SharePoint list to a file. .DESCRIPTION Exports all items from a SharePoint list to a file. .PARAMETER List The human readable list name. So 'My List' as opposed to 'MyList', unless you named it MyList. .PARAMETER Web The human readable web name. So 'My Web' as opposed to 'MyWeb', unless you named it MyWeb. .PARAMETER Site The address to the site collection. You can also pass a hostname and it'll figure it out. Don't want to specify the Site or Credential every time? Use Connect-SPRSite to create a reusable connection. See Get-Help Connect-SPRsite for more information. .PARAMETER Credential Provide alternative credentials to the site collection. Otherwise, it will use default credentials. .PARAMETER Path The target dat (compressed xml) file location. .PARAMETER LogToList You can log imports and export results to a list. Note this has to be a list from Get-SPRList. .PARAMETER InputObject Allows piping from Get-SPRList or Get-SPRListItem .PARAMETER EnableUserField Only relevant when using -AutoCreateList for Imports or Adds. By default, User fields will be exported as string fields. Use this to keep the User field datatype. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .EXAMPLE Export-SPRListItem -Site intranet.ad.local -List 'My List' -Path C:\temp\mylist.dat Exports all items from My List on intranet.ad.local to C:\temp\mylist.dat .EXAMPLE Get-SPRListItem -List 'My List' -Site intranet.ad.local |Export-SPRListItem -Path C:\temp\mylist.dat Exports all items from My List on intranet.ad.local to C:\temp\mylist.dat #> [CmdletBinding()] param ( [Parameter(Position = 0, HelpMessage = "Human-readble SharePoint list name")] [string]$List, [Parameter(Position = 1, HelpMessage = "Human-readble SharePoint web name")] [string]$Web, [Parameter(Position = 2, HelpMessage = "SharePoint Site Collection")] [string]$Site, [PSCredential]$Credential, [Parameter(Mandatory)] [string]$Path, [Microsoft.SharePoint.Client.List]$LogToList, [parameter(ValueFromPipeline)] [object]$InputObject, [switch]$EnableUserField, [switch]$EnableException ) begin { $collection = @() $start = Get-Date } process { if (-not $InputObject) { if ($Site) { $InputObject = Get-SPRListItem -Site $Site -Credential $Credential -List $List -Web $Web } elseif ($script:spsite) { $InputObject = Get-SPRListItem -List $List -Web $Web } else { $failure = $true Stop-PSFFunction -EnableException:$EnableException -Message "You must specify Site and List pipe in results from Get-SPRList" return } } if ($InputObject -is [Microsoft.SharePoint.Client.List]) { $InputObject = $InputObject | Get-SPRListItem } $collection += $InputObject } end { try { $columns = $collection | Select-Object -First 1 -ExpandProperty ListObject | Get-SPRColumnDetail | Where-Object { -not $psitem.Hidden -and -not $PSItem.ReadOnly -and $PSItem.Type -notin 'Computed', 'Lookup' -and $PSItem.Name -notin 'Created', 'Author', 'Editor', '_UIVersionString', 'Modified', 'Attachments' } $spdatatype = $columns | Select-SPRObject -Property Name, 'TypeAsString as Type' if (-not $EnableUserField) { $tempdatatype = @() foreach ($dt in $spdatatype) { $name = $dt.Name $type = $dt.Type if ($type -eq 'User') { $type = 'Text' } $tempdatatype += [pscustomobject]@{ Name = $name Type = $type } } $spdatatype = $tempdatatype } $columnsnames = $columns.Name | Select-Object -Unique [PSCustomObject]@{ SPReplicatorDataType = $spdatatype Data = $collection | Select-Object -Property $columnsnames } | Export-PSFClixml -Path $Path Get-ChildItem -Path $Path -ErrorAction Stop } catch { $failure = $true Stop-PSFFunction -EnableException:$EnableException -Message "Failure" -ErrorRecord $_ } if ($LogToList) { $thislist = $InputObject | Select-Object -First 1 -ExpandProperty ListObject if ($thislist) { $thislist.Context.Load($thislist) $thislist.Context.ExecuteQuery() $thislist.Context.Load($thislist.RootFolder) $thislist.Context.ExecuteQuery() $url = "$($thislist.Context.Url)$($thislist.RootFolder.ServerRelativeUrl)" $currentuser = $thislist.Context.CurrentUser.ToString() } else { $currentuser = $script:spsite.CurrentUser.ToString() } if ($failure) { $result = "Failed" $errormessage = Get-PSFMessage -Errors | Select-Object -Last 1 -ExpandProperty Message } else { $result = "Succeeded" } $elapsed = (Get-Date) - $start $duration = "{0:HH:mm:ss}" -f ([datetime]$elapsed.Ticks) [pscustomobject]@{ Title = $thislist.Title ItemCount = ($collection).Count Result = $result Type = "Export" RunAs = $currentuser Duration = $duration URL = $url FinishTime = Get-Date Message = $errormessage } | Add-LogListItem -ListObject $LogToList -Quiet } } } |
