How to convert PDF to Excel or CSV in Rails 4

Question

I have searched a lot. I have no choice unless asking this here. Do you guys know an online convertor which has API or Gem/s that can convert PDF to Excel or CSV file?

Answer 1

Ryan Bates covers csv exports in his rails casts > http://railscasts.com/episodes/362-exporting-csv-and-excel this might give you some pointers.

Edit: as you now mention you need the raw data from an uploaded PDF, you could use JavaScript to read the PDF file and the populate the data into Ryan Bates' export method. Reading PDF's was covered excellently in the following question:

extract text from pdf in Javascript

I would imagine the flow would be something like:

PDF new action
    user uploads PDF 

PDF show action
    PDF is displayed
    JavaScript reads PDF
    JavaScript populates Ryan's raw data
    Raw data is exported with PDF data included
