@nethmi You can use code like the following to remove empty paragraphs from your document:

Document doc = new Document(@"C:\Temp\in.docx");

NodeCollection paragraphs = doc.GetChildNodes(NodeType.Paragraph, true);
foreach (Paragraph p in paragraphs)
{
    // If paragraph has empty text, there might be a shape, or bookmark
    // Copy content to the next or previous paragraph.
    if (string.IsNullOrEmpty(p.ToString(SaveFormat.Text).Trim()))
    {
        if (p.NextSibling != null && p.NextSibling.NodeType == NodeType.Paragraph)
            while (p.HasChildNodes)
                ((Paragraph)p.NextSibling).PrependChild(p.LastChild);

        if (p.PreviousSibling != null && p.PreviousSibling.NodeType == NodeType.Paragraph)
            while (p.HasChildNodes)
                ((Paragraph)p.PreviousSibling).AppendChild(p.FirstChild);
    }

    // Empty paragraphs can be removed.
    if (!p.HasChildNodes)
        p.Remove();
}

doc.Save(@"C:\Temp\out.docx");

Hii team,

Now It’s working. But I got a new issue.issue.PNG (126.2 KB)

expected output isexpected.PNG (138.9 KB)

Could you please check that??

@nethmi You can try removing only actually empty paragraphs:

NodeCollection paragraphs = doc.GetChildNodes(NodeType.Paragraph, true);
foreach (Paragraph p in paragraphs)
{
    // Empty paragraphs can be removed.
    if (!p.HasChildNodes)
        p.Remove();
}

Or remove only paragraphs that do not contain shapes:

NodeCollection paragraphs = doc.GetChildNodes(NodeType.Paragraph, true);
foreach (Paragraph p in paragraphs)
{
    // Empty paragraphs can be removed.
    if (string.IsNullOrEmpty(p.ToString(SaveFormat.Text).Trim()) &&
        p.GetChildNodes(NodeType.Shape, true).Count == 0)
        p.Remove();
}

hii Team.

my second issue is still not solved. because both problems are occurring with the shapes. Could you please give me a implementation only for paragraphs with wrapped images???

//this is my method implementation for wrapping

private static void SetImageLayout(Document document, HtmlDocument htmlDocument)
    {
        HtmlNodeCollection images = htmlDocument.DocumentNode.SelectNodes("//img");           
        NodeCollection shapes = document.GetChildNodes(NodeType.Shape, true);
                   
        if (images != null)
        {
            var imgIndex = 0;
            foreach (Shape shape in shapes)
            {
                var image = images.ElementAt(imgIndex);

                if (image.HasClass("fr-fil")) 
                {
                    shape.WrapType = WrapType.Square;                      
                }
                else
                {
                    shape.HorizontalAlignment = HorizontalAlignment.Center;
                } 
                shape.AllowOverlap = false;
                imgIndex++;
            }
        }
    }

or do you have any suggestions??

@nethmi You can modify your code like the following to skip paragraphs that contain inline shapes:

NodeCollection paragraphs = doc.GetChildNodes(NodeType.Paragraph, true);
foreach (Paragraph p in paragraphs)
{
    // If paragraph has empty text, there might be a shape, or bookmark
    // Copy content to the next or previous paragraph.
    if (string.IsNullOrEmpty(p.ToString(SaveFormat.Text).Trim()))
    {
        // Skip paragraphs with inline shapes.
        NodeCollection shapes = p.GetChildNodes(NodeType.Shape, true);
        foreach (Shape s in shapes)
            if (s.WrapType == WrapType.Inline)
                continue;

        if (p.NextSibling != null && p.NextSibling.NodeType == NodeType.Paragraph)
            while (p.HasChildNodes)
                ((Paragraph)p.NextSibling).PrependChild(p.LastChild);

        if (p.PreviousSibling != null && p.PreviousSibling.NodeType == NodeType.Paragraph)
            while (p.HasChildNodes)
                ((Paragraph)p.PreviousSibling).AppendChild(p.FirstChild);
    }

    // Empty paragraphs can be removed.
    if (!p.HasChildNodes)
        p.Remove();
}
