Introduction

Creating a large number of folders manually in a SharePoint Online document library can be time-consuming and inefficient. If you need to create hundreds of folders or subfolders for projects, departments, or structured document management, using PnP PowerShell is the fastest and most scalable approach.

In this guide, you’ll learn how to bulk create folders in a SharePoint document library using PnP PowerShell step-by-step.

Using PnP PowerShell, you can:
