need to convert a pdf file to a doc file. I found different type of example to generate pdf file but not got pdf to doc.
What your asking is actually very difficult
I recommend you start here and look for a good parsing library. then you would have to write it out in .doc format. Inevitably a lot of the formatting and extra information would be lost. it would be a lot easier to output to docx format, but i assume thats not what your looking for.
