I have an asp.net 4 application that generate a pptx file from a pptx template where data is replaced with data retrieved from a database. It works well before but since few days with no code change, the pptx generated doesn't have a correct format. When openning it I have a message to repair it. When I repair it, all the boxplot charts disapear.
Anyone have had the same issue ?
Any issue related to repair the pptx files comes only when your file is having any correpted xml node data.
Use open xml productivity tool for these kind of issue. It will show you the currepted node.
Note: hope you know how to use it.
Thnak you for replying.
I install open xml productivity tool, I open the corrupted file and I click on the validate button but the result is that there is no validation error found.
we didn't find the solution for this problem, but the customer wants to generate pdf instead of pptx.
How can I do that with openxml ?
