private void btnFillData_Click(object sender, EventArgs e)
    using (OpenFileDialog ofd = new OpenFileDialog() { Filter = "PowerPoint |*.pptx" })
        if (ofd.ShowDialog() == DialogResult.OK)
            FileInfo fileInfo = new FileInfo(ofd.FileName);
            string fileName = $"{fileInfo.Directory}\\{fileInfo.Name.Replace(fileInfo.Extension, "")}_data{fileInfo.Extension}";
            File.Copy(ofd.FileName, fileName);
            Pptx pptx = new Pptx(fileName, FileAccess.ReadWrite);
            int totalSlide = pptx.SlidesCount();
            if (totalSlide > 0)
                PptxSlide slide = pptx.GetSlide(0);//default slide 0
                slide.ReplaceTag("{{fullname}}", txtFullName.Text, PptxSlide.ReplacementType.Global);
                slide.ReplaceTag("{{email}}", txtEmail.Text, PptxSlide.ReplacementType.Global);
                slide.ReplaceTag("{{address}}", txtAddress.Text, PptxSlide.ReplacementType.Global);

We will open the powerpoint template file, then copy it to another file and finally fill the data into the fields that we have defined.
