To use PowerShell to download files from SharePoint, you can first connect to the SharePoint site using the SharePoint Online Management Shell. Once connected, you can use the Get-PnPFile command to retrieve files from a document library in SharePoint. You will need to specify the URL of the document library and the file path of the file you want to download. You can also specify the local path where you want to save the downloaded file. After running the command, PowerShell will download the file from SharePoint to your local computer.
What are some best practices for using Powershell with SharePoint?
- Use PowerShell ISE for scripting: PowerShell ISE provides an environment that enables users to write and test PowerShell scripts more efficiently, offering features like syntax highlighting, code completion, and debugging tools.
- Use SharePoint Management Shell: The SharePoint Management Shell is a specialized PowerShell prompt that comes with SharePoint, offering cmdlets specific to SharePoint administration tasks. It is recommended to use this shell for any SharePoint-related scripting.
- Use PowerShell Remoting: PowerShell remoting allows users to execute PowerShell commands on remote SharePoint servers, making it easier to manage multiple servers and automate tasks across the SharePoint farm.
- Use error handling: Implement error handling in PowerShell scripts to catch and handle any errors that may occur during script execution. This ensures that the script will not fail completely if an error occurs, and provides a more robust and reliable automation solution.
- Use SharePoint Online Management Shell for SharePoint Online: If you are working with SharePoint Online, use the SharePoint Online Management Shell, which provides cmdlets specific to SharePoint Online administration tasks.
- Use the SharePoint PowerShell Module: The SharePoint PowerShell Module provides additional cmdlets and functionalities for managing SharePoint, and can be imported into PowerShell scripts to extend their capabilities.
- Keep scripts modular and reusable: Divide PowerShell scripts into modular functions that can be reused in other scripts, making it easier to maintain and update scripts over time. This also allows for better organization and readability of scripts.
- Document scripts: Document PowerShell scripts with comments and annotations to explain the purpose of each section of code, as well as any parameters or assumptions. This helps other users understand and maintain the scripts in the future.

- After the installation is complete, you can launch Powershell by searching for it in the start menu or by opening a command prompt and typing "powershell."
That's it! Powershell should now be installed and ready to use on your Windows system.
How to download files from multiple SharePoint sites using Powershell?
To download files from multiple SharePoint sites using PowerShell, you can use the following script:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
# Connect to SharePoint Online Connect-PnPOnline -Url https://yourtenant.sharepoint.com/sites/site1 $cred = Get-Credential # Specify the list of SharePoint sites $sites = @("https://yourtenant.sharepoint.com/sites/site1", "https://yourtenant.sharepoint.com/sites/site2") # Loop through each SharePoint site foreach ($site in $sites) { # Connect to the SharePoint site Connect-PnPOnline -Url $site -Credentials $cred # Get all files from the document library (you can specify the library name if needed) $files = Get-PnPListItem -List "Documents" # Loop through each file and download it foreach ($file in $files) { $fileUrl = $file.FieldValues.FileRef $fileName = $file.FieldValues.FileLeafRef $filePath = "C:\Downloads\$fileName" # Download the file Get-PnPFile -Url $fileUrl -Path $filePath -AsFile } } |
In the above script, you will need to replace https://yourtenant.sharepoint.com/sites/site1
and https://yourtenant.sharepoint.com/sites/site2
with the URLs of the SharePoint sites you want to download files from. Make sure you have the necessary permissions to access these sites.
You can also customize the script to specify the document library from which you want to download files. Just replace "Documents"
with the name of your document library.
To run the script, save it as a .ps1 file and execute it using PowerShell. Make sure you have the SharePoint Online Management Shell module installed and are connected to the SharePoint site using Connect-PnPOnline
before executing the script.
What is Powershell and how does it work?
PowerShell is a powerful scripting language and automation framework developed by Microsoft for task automation and configuration management. It is built on top of the .NET framework and allows users to automate tasks and manage systems from the command line or through scripts.
PowerShell works by using cmdlets (pronounced command-lets), which are small, single-function command-line utility programs that perform specific tasks. These cmdlets can be used individually or chained together to perform more complex operations. Users can also create their own cmdlets using PowerShell scripting.
PowerShell also supports object-oriented programming, meaning that the output of one cmdlet can be piped into another cmdlet as input, allowing for a more seamless and efficient workflow. Additionally, PowerShell supports remote management, allowing users to manage multiple systems from a single console.
Overall, PowerShell provides a more powerful and flexible alternative to traditional command-line interfaces, making it a valuable tool for system administrators and IT professionals.
