DOCX Compare features

The DOCX Compare C# library allows for comparing two Word document versions to identify differences using revision marks.

It offers various customization options including the ability to specify comparison granularity at the word or character level, whether to compare formatting, case changes, whitespace, tables, headers and footers, footnotes and endnotes, textboxes, fields, comments, document moves, and whether to accept revisions before comparison.

This is useful for efficiently managing document revisions in collaborative environments such as legal, academic, and corporate settings.
