Accept or reject detected changes Leave feedback
On this page
GroupDocs.Comparison for Python via .NET lets you programmatically accept or reject individual changes before producing the final result.
Compare files, update change actions, and apply them to the output.
import groupdocs.comparison as gc
with gc.Comparer("source.docx") as comparer:
comparer.add("target.docx")
comparer.compare()
changes = comparer.get_changes()
# Example: reject the first change
if changes:
changes[0].comparison_action = gc.ComparisonAction.REJECT
with open("result.docx", "wb") as out_stream:
comparer.apply_changes(out_stream, gc.ApplyChangeOptions(changes=changes))
🔹 Use case: Remove undesired edits from the final deliverable while keeping approved changes.
The result is as follows:
| Accepted changes | Rejected changes |
|---|---|
 |  |
Work entirely with streams and persist the merged result.
import groupdocs.comparison as gc
with open("source.docx", "rb") as src, open("target.docx", "rb") as tgt:
with gc.Comparer(src) as comparer:
comparer.add(tgt)
comparer.compare()
changes = comparer.get_changes()
if changes:
changes[0].comparison_action = gc.ComparisonAction.REJECT
with open("result.docx", "wb") as out_stream:
comparer.apply_changes(out_stream, gc.ApplyChangeOptions(changes=changes))
🔹 Use case: Integrate approval workflows in services that don’t use local file paths.
