Remove Hidden Text from Document

On this page we will look at how to remove hidden text from a document using Aspose.Words or Open XML SDK.

Aspose.Words

In Aspose.Words, use the ParagraphBreakFont and the Hidden properties to find all hidden text.

The following code example shows how to remove hidden text from a Word Document:

// For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-.NET.git.
Document doc = new Document(MyDir + "Remove hidden text.docx");
            
foreach (Paragraph para in doc.GetChildNodes(NodeType.Paragraph, true))
{
    para.ParagraphBreakFont.Hidden = false;
    foreach (Run run in para.GetChildNodes(NodeType.Run, true))
    {
        if (run.Font.Hidden)
            run.Font.Hidden = false;
    }
}

doc.Save(ArtifactsDir + "Remove hidden text - Aspose.Words.docx");

Open XML SDK

You can also do the same using the Open XML SDK. At the same time, note that it looks somewhat more complicated and more cumbersome.

The following code example shows how to remove hidden text from a Word document:

// For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-.NET.git.
File.Copy(MyDir + "Remove hidden text.docx", ArtifactsDir + "Remove hidden text - OpenXML.docx", true);

using WordprocessingDocument doc = WordprocessingDocument.Open(ArtifactsDir + "Remove hidden text - OpenXML.docx", true);
foreach (Paragraph paragraph in doc.MainDocumentPart.Document.Body.Elements<Paragraph>())
{
    // Iterate through all runs in the paragraph.
    foreach (Run run in paragraph.Elements<Run>())
    {
        // Check if the run has properties
        RunProperties runProperties = run.RunProperties;
        if (runProperties != null)
        {
            // Check if the text is hidden.
            Vanish hidden = runProperties.Elements<Vanish>().FirstOrDefault();
            if (hidden != null)
                // Remove the hidden property to unhide the text.
                hidden.Remove();
        }
    }
}
