How to get an export option as a pdf for views?
Try Views Pdf module 

Descriptoin about viewspdf module: 


  With this module you can output a view as a PDF document. Each field of the view can be placed on the PDF page directly in the
  administration interface. Therefore a new display called "PDF" is
  added.
  
  There are already some PDF solutions such as Print. But these solutions use the HTML output and converts this to PDF. The downsides
  of such an integration are:
  
  No control over page flow (e.g. page break).
  Little or no control over page header and footer.
  You need HTML skills to change the layout.
  The rendering is slow and need a lot of memory, because it needs to render the HTML.
  Complex tables make troubles.
  Vector graphics can not be implemented, therefore the printing of the document can be problematic.
  You are limited by HTML's capabilities.
  No hyphenation.
  
  You can also specify a background PDF document. This enables you to put unlimited static content to the dynamic PDF. This static PDF
  can be exchanged dynamically by using a File Field. The PDF can be
  created by any PDF creator such as Adobe Acrobat Professional or Open
  Office.
