Clippit is a .NET library for programmatically creating, modifying, and converting
Word (DOCX), Excel (XLSX), and PowerPoint (PPTX) documents. Built on top of the
[Open XML SDK](https://github.com/OfficeDev/Open-XML-SDK), it provides high-level
APIs that handle the complexity of the Open XML format so you can focus on your content.
It also includes a scriptable CLI for PowerPoint split/build/verify workflows,
manifest-driven Word build/compare/consolidate workflows, DOCX template
assembly and markup cleanup, DOCX↔HTML conversion, and XLSX create/verify
workflows.
