The file conversion solution!
So... Last night, I was dealing with a stupid pdf file, this one in particularly was having a core data for a my next app, a perfectly well formed xls inside a stupid pdf file, the solution: http://www.zamzar.com/ In seconds I was able to convert every file to xls, now the next problem after export the formatted xls to csv, was the conversion to json itself. That I resolve with this web app: http://www.convertcsv.com/csv-to-json.htm So the steps are various, but the effort its minimal. Good luck with your conversions! bye
