Aspose.Slides and Aspose.Words

To convert a PowerPoint file (PPTX or PPT) to Word (DOCX or DOCX), you need both Aspose.Slides for .NET and Aspose.Words for .NET.

As a standalone API, Aspose.Slides for .NET provides functions that allow you to extract texts from presentations.

Aspose.Words is an advanced document processing API that allows applications to generate, modify, convert, render, print files, and perform other tasks with documents without utilizing Microsoft Word.
