  2. Document Cleanliness:
    • Clears unnecessary or outdated metadata.
  3. Compliance and Security:
    • Supports compliance with privacy regulations.

Prerequisites: Preparing the Environment

  1. Set up Visual Studio or any compatible .NET IDE.
  2. Include the Aspose.Words library available through NuGet Package Manager.

Step-by-Step Guide to Remove Metadata from Word Documents Using C#

Step 1: Configure Aspose.Words via NuGet

Set up Aspose.Words library in your project using the NuGet package manager.

Install-Package Aspose.Words

Step 2: Load the Word Document

Load the Word file you want to remove metadata from using the Document class.

Document doc = new Document("SampleProps.doc");

Step 3: Access Custom Properties

Get access to the custom properties collection via CustomDocumentProperties class object.

CustomDocumentProperties customProps = doc.CustomDocumentProperties;

Step 4: Clear Custom Properties

Remove custom metadata from the Word file by calling Clear().

customProps.Clear();

Step 5: Access Built-in Properties

Access built-in properties using the BuiltInDocumentProperties object.

BuiltInDocumentProperties builtInProps = doc.BuiltInDocumentProperties;

Step 6: Clear Built-in Properties

Call Clear() to remove the values of all built-in properties.

builtInProps.Clear();

Step 7: Save the Document Without Metadata

After metadata removal, save your document back to disk.

doc.Save("Output.doc");

Complete Code Example to Remove Metadata in Word Using C#

Below is the full executable example

// Load the Word file
Document doc = new Document("SampleProps.doc");

// Access the custom properties and clear them
CustomDocumentProperties custProps = doc.CustomDocumentProperties;
custProps.Clear();

// Access the built-in properties and clear their values
BuiltInDocumentProperties builtInProps = doc.BuiltInDocumentProperties;
builtInProps.Clear();

// Save the Word file after metadata removal
doc.Save("Output.doc");

System.Console.WriteLine("Metadata removed successfully.");

Additional Information

  • Use the Remove() method with a property name to delete individual custom or built-in property values specifically.
  • Use the RemoveAt() method by providing an index to delete properties based on their index in the collection.
