PowerShell でSharePoint Data データをCSV に落としてみた

標準PowerShell cmdlets を使ってSharePoint テーブルにアクセス。

CData Cmdlets Module for SharePoint は、直感的なSharePoint データ連携を提供する標準cmdlet です。 本記事では、SharePoint Cmdlets を使ったサンプルを提供します。

Creating a Connection to Your SharePoint Data

Set the URL property to the base SharePoint site or to a sub-site. This allows you to query any lists and other SharePoint entities defined for the site or sub-site.

The User and Password properties, under the Authentication section, must be set to valid SharePoint user credentials when using SharePoint On-Premise.

If you are connecting to SharePoint Online, set the SharePointEdition to SHAREPOINTONLINE along with the User and Password connection string properties. For more details on connecting to SharePoint Online, see the "Getting Started" chapter of the help documentation

$conn = Connect-SharePoint  -User "$User" -Password "$Password" -Auth Scheme "$Auth Scheme" -URL "$URL" -SharePointEdition "$SharePointEdition"

Selecting Data

Follow the steps below to retrieve data from the MyCustomList table and pipe the result into to a CSV file:

Select-SharePoint -Connection $conn -Table MyCustomList | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myMyCustomListData.csv -NoTypeInformation

You will notice that we piped the results from Select-SharePoint into a Select-Object cmdlet and excluded some properties before piping them into an Export-Csv cmdlet. We do this because the CData Cmdlets append Connection, Table, and Columns information onto each "row" in the result set, and we do not necessarily want that information in our CSV file.

The Connection, Table, and Columns are appended to the results in order to facilitate piping results from one of the CData Cmdlets directly into another one.

Deleting Data

The following line deletes any records that match the criteria:

Select-SharePoint -Connection $conn -Table MyCustomList -Where "Location = Chapel Hill" | Remove-SharePoint

Inserting and Updating Data

The cmdlets make data transformation easy as well as data cleansing. The following example loads data from a CSV file into SharePoint, checking first whether a record already exists and needs to be updated instead of inserted.

Import-Csv -Path C:\MyMyCustomListUpdates.csv | %{
  $record = Select-SharePoint -Connection $SharePoint -Table MyCustomList -Where ("Id = `'"+$_.Id+"`'")
    Update-SharePoint -Connection $sharepoint -Table MyCustomList -Columns ("Name","Revenue") -Values ($_.Name, $_.Revenue) -Where ("Id = `'"+$_.Id+"`'")
    Add-SharePoint -Connection $sharepoint -Table MyCustomList -Columns ("Name","Revenue") -Values ($_.Name, $_.Revenue)

As always, our goal is to simplify the way you connect to data. With cmdlets users can install a data module, set the connection properties, and start building. Download Cmdlets and start working with your data in PowerShell today!
