GroupDocs.Signature provides a powerful engine for detecting digital signatures in XLSX files. Python via .NET developers can easily enhance their apps with this functionality.
import groupdocs.signature as sg
def run():
# Initialize a Signature object with the document's file path
with sg.Signature('input.xlsx') as signature:
# Create an instance of TextSearchOptions to search all pages
options = sg.TextSearchOptions()
options.AllPages = True
# Run a search to locate any text-based signatures in the document
signatures = signature.Search(options)
print("\nSource document contains following text signature(s).")
# Compile a list of found signatures for detailed review
for textSignature in signatures:
print("\nFound Text signature at page ", textSignature.PageNumber)
Experience a powerful, feature-rich signing solution that secures your documents with multiple signature types, spanning various file formats.
Add electronic signatures anywhere in a document. GroupDocs.Signature supports multiple signature types, including text, images, barcodes, metadata, stamps, and digital certificates, ensuring the document’s authenticity and security.
Once a document is signed, use the search feature to find all embedded signatures. You can modify or remove signatures as needed, giving you full control over the document’s integrity.
Use advanced tools to manage hidden metadata within documents. Add or remove metadata, and apply digital certificates to safeguard your documents from unauthorized changes, ensuring their authenticity.
import groupdocs.signature as sg
def run():
# Pass the source document to the constructor
with sg.Signature('input.xlsx') as signature:
# Search for any text-based signatures
signatures = signature.Search(sg.SignatureType.Image)
print("\nSource document contains following image signature(s).")
# Display detailed properties of the identified signatures
for imageSignature in signatures:
print("\nFound image signature at page ", imageSignature.PageNumber)
