Extract list from Sharepoint without using Get-SPWeb - powershell

Question

I don't have access to the Sharepoint server and can't use remoting, and therefore don't have access to Microsoft.Sharepoint.Powershell which contains the SharePoint commandlets.
I also can't use 3rd party libraries which means I only have access to built in Powershell commandlets, or any .NET class.
How can I access a Sharepoint list using only built in Powershell commandlets or .NET classes?

Answer 1

Well if you are using SharePoint 2010 and you don't have access to the server itself and must interact with it remotely you have essentially three options:

You can use:
Client Side Object Model - this gives you a structured SharePoint classes approach to enumerating, viewing and interacting with SharePoint site artifacts
SOAP Web Services - Exactly what it sounds like...a set of XML SOAP end points that let you interact with a SharePoint site
REST Web Services - A set of endpoints that follow REST principles
FWIW, the CSOM libraries use the REST endpoints under the covers.

Answer 2

In given scenario you can make use of PnP Powershell which runs on client side. You just need to install small setup to enable PnP command on machine from where you will run Powershell.
Then you can use command Connect-PnPOnline to connect to desired sharepoint site.
PS:> Connect-PnPOnline -Url https://contoso.sharepoint.com
Once you provide valid credentials you will have access to PnP Context for that particular site.
Then using Get-PnPList command you can fetch list data
PS:> Get-PnPList -Identity Lists/Announcements
For more information on PnP-Powershell please refer Documentation : https://github.com/SharePoint/PnP-PowerShell/tree/master/Documentation
Hope it will help you..:)
