Hi Yuan,

Thank you for posting.

I have observed your comments and worked with the presentation file shared by you. I am getting the exception as “Input string was not in correct format” for the attached file “3810b830-3e76-4598-8ad8-af46eceff4e0.ppt”. Please verify if you are getting the same error for this file or “Unknown file format” error on your end. I will be able to proceed further once the requested information is shared by you.

Best Regards,
