title: How to convert Word and Excel documents to PDF programmatically?
body: <p>We are developing a little application that given a directory with PDF files creates a unique PDF file containing all the PDF files in the directory. This is a simple task using iTextSharp. The problem appears if in the directory exist some files like Word documents, or Excel documents.</p>
  
  <p>My question is, is there a way to convert word, excel documents into PDF programmatically? And even better, is this possible without having the office suite installed on the computer running the application?</p>
