Hey @kartikdutt18, I will add json. xml -> csv by the end of today or tomorrow... I will also keep in mind the edits you suggested in here...

Hey @kartikdutt18, I noticed something... If you go to the example here to see how the convert function works you can see that we gave an input .csv file with 10 rows and we got 1 XML file per row as output making total to 10 .xml files as output, is this right? Or do we also want an option to put all these in the same .xml file?

Shouldn't we have to put all of them in 1 file?

Also, we are planning to reduce boost dependencies, right? So should we use boost here?
