Overview

This feature allows you to access and extract external CSS stylesheets embedded within a Word document using GroupDocs.Editor, enabling further manipulation or integration into your web applications.

Step 1: Initialize the Editor with Your Document

Begin by initializing the Editor class with the path to your Word document. This step is crucial as it prepares your document for editing and extraction operations.
