Q: Edit docx, pptx, xlsx files in iOS Sdk He All,
I want to edit docx, xlsx and pptx files on iPad. I have done so many research on this. I have found one formate called "OOXML" formate  which which is responsible for the same.
Ecma-376 standards
They have mentioned the ebooks for understanding the OOXML format. It is useful resource.
But my Problem is how I can manage to do the same in the iOS as there are so many apps are on the appStore which are manage to do the same. So there is a way by which we can edit dock,pptx,xlxs and save them on the iOs.
Can any one have idea or some reference or library which is able to do the same. 
I have also seen the libopc library.
libopc documentation
Thanks.
