How to remove unused style in word document


I have to find out the unused style in the document and then remove them before I output the document to the user.

sample code :

foreach (Aspose.Words.Style style in doc.Styles)
if (!style.BuiltIn)
//ToDo: Identify if style is not used and remove it

Just wondering why there is no style.Remove() method?

Thanks for your request. You are right, currently there is no way to remove styles from the document. Your request has been linked to the appropriate issue. You will be notified as soon as this feature is available.

Best regards.

The issues you have found earlier (filed as WORDSNET-3291) have been fixed in this .NET update and this Java update.

Hi Guido,

Thanks for your inquiry. The RemoveUnusedResources method was added to Document class to remove any unused styles and lists from the document. Please try run the following code:

Document doc = new



I hope, this helps.

Best regards,


Starting from Aspose.Words 21.4, you can remove unused built-in styles from document using CleanupOptions.UnusedBuiltinStyles property. Following code snippet shows how to use this property.

Document doc = new Document("input.docx");
CleanupOptions cleanupOptions = new CleanupOptions();
cleanupOptions.UnusedBuiltinStyles = true;
