How should I convert ppt slideshow to pptx programatically using c#.

I don't want to install office on server side for this action , I want to find a way without using Microsoft.Office.Interop.PowerPoint.

Any suggestions ?

Here is another suggestion, this PowerPoint library for C#.
To achieve that conversion with it you simply need to use the following:

PresentationDocument presentation = PresentationDocument.Load("Input.ppt");

Also you can refer to a following example as well which shows how to load / save PPTX in C# / VB.NET.

You can use b2xtranslator for that, you can find it on sourceforge[^]

Renaming the file mentioned above isn't the solution, a PPT file is a binary compound storage file and a PPTX is more like a ZIP file.

I'm not sure it's still true with the latest version of power point, but we just used to rename the file. It's all based on the filename extension.
