Chevy Saw your code when you are using dd/mm/yyyy you are getting a date. Not sure if you are trying to edit on same date. Alos no code seen for replacement!

Thanks for your reply. You have right: string fileName = @C:\Inetpub\wwwroot\pptx\ppt1.pptx; using (PresentationDocument prstDoc = PresentationDocument.Open(ppt1.pptx true)) { string newValue = DateTime.Now.ToString(MMMM dd yyyy); foreach (SlidePart sPart in prstDoc.PresentationPart.SlideParts) { Slide sld = sPart.Slide; var datePlaceholders = sld.CommonSlideData.ShapeTree.ChildElements.OfType (). Where(s => s.NonVisualShapeProperties.NonVisualDrawingProperties.Name.Value == Date Placeholder 3); if (datePlaceholders != null) { datePlaceholders.ToList().ForEach(datePlaceholder=> { datePlaceholder.InsertNewValue(newValue); }); } } prstDoc.PresentationPart.Presentation.Save(); }
