  1. I tried to used the TabStops property but its not working. Please find the below code.
NodeCollection nodes = doc.GetChildNodes(NodeType.Paragraph, true);
foreach (Paragraph para in nodes)
{
    if (para.ParagraphFormat.StyleIdentifier == StyleIdentifier.Heading2)
    {
        para.ParagraphFormat.FirstLineIndent = ConvertUtil.InchToPoint(-0.4);
        para.ParagraphFormat.LeftIndent = -para.ParagraphFormat.FirstLineIndent;

        para.ParagraphFormat.TabStops.Add(0.4, TabAlignment.Left, TabLeader.None);

    }
}

Any update on this?

@Princeshivananjappa Your code properly creates a tab stop in Heading 2 paragraphs:

Please not Aspose.Words uses Points as measurement units, in your case it looks like you use Inches. So you should use ConvertUtil to convert the units.
