Hi,
I'll implement a php to read your url and create a csv file, so that the created csv file will be downloaded to you. Since you've mentioned it's a pdf file, I might face a problem to read it directly. I'll use PDF Parser jars to read it.
I've done a similar job 2 days ago (https://www.freelancer.com/projects/XML/Parsing-API-Data/). It converts json file into csv. I've completed that task in just 1 day using php and the client is checking it(he does not have configured php in his machine, so working on it). If you need I can show a sample file that got created in my machine.
Thanks & Regards,
Indika
