Annotation redactions Leave feedback
On this page
With GroupDocs.Redaction API you can apply annotation redactions for documents of different formats like PDF, DOC, DOCX, PPT, PPTX, XLS, XLSX and others. See full list at supported document formats article.
GroupDocs.Redactions provides a flexible API that allows to remove sensitive data from annotation text, or completely remove annotations by a regular expression.
You can use GroupDocs.Redaction to remove all or specific comments and other annotations from the document. For example, we can remove all comments from the document, containing texts like “use”, “show” or “describe” in its body:
from groupdocs.redaction import Redactor
from groupdocs.redaction.options import SaveOptions
from groupdocs.redaction.redactions import DeleteAnnotationRedaction
def remove_all_annotations():
# Specify the redaction options to delete annotations matching the pattern
a_red = DeleteAnnotationRedaction("(?im:(use|show|describe))")
# Load the document to be redacted
with Redactor("./annotated.xlsx") as redactor:
# Apply the redaction
result = redactor.apply(a_red)
# Save the redacted document next to the source file
so = SaveOptions()
so.add_suffix = True
so.rasterize_to_pdf = False
so.redacted_file_suffix = "redacted"
redactor.save(so)
if __name__ == "__main__":
remove_all_annotations()

You can use constructor without arguments to remove all annotations within the document.
Instead of removing all or specific annotations, you can remove sensitive data from the annotation text. For instance, we can remove all mentions of “John” in the given document, e.g.:
from groupdocs.redaction import Redactor
from groupdocs.redaction.options import SaveOptions
from groupdocs.redaction.redactions import AnnotationRedaction
def redact_annotations():
# Specify the redaction options: search pattern and replacement string
a_red = AnnotationRedaction("(?im:john)", "[redacted]")
# Load the document to be redacted
with Redactor("./annotated.xlsx") as redactor:
# Apply the redaction
result = redactor.apply(a_red)
# Save the redacted document next to the source file
so = SaveOptions()
so.add_suffix = True
so.rasterize_to_pdf = False
so.redacted_file_suffix = "redacted"
redactor.save(so)
if __name__ == "__main__":
