Compare Word Documents Leave feedback

GroupDocs.Comparison for Python via .NET compares Word documents and highlights differences in text, formatting, styles, and structure. Typical use cases include legal contracts, business reports, and any collaborative editing workflow where accurate change tracking matters.

The API:

• Compares DOC and DOCX files (and Word-compatible formats such as RTF, ODT, DOT, DOTX).
• Highlights insertions, deletions, and formatting changes.
• Exports the result as a Word document or any other supported format.

1. Create a Comparer instance and load the source Word document.
2. Add one or more target Word documents via add().
3. Call compare() to generate the result file.

from groupdocs.comparison import Comparer

def compare_word_documents():
    with Comparer("./source.docx") as comparer:
        comparer.add("./target.docx")
        comparer.compare("./result.docx")

if __name__ == "__main__":
    compare_word_documents()

The base flow above works for any Word format, but several options on CompareOptions are specifically useful when comparing Word documents:

• Accept or reject detected changes — apply only the changes you want.
• Accept or reject revisions — process Word Track Changes revisions independently of comparison.
• Customize changes styles — change colours and decorations for inserted/deleted/changed items.
