Not yet. Currently it can read delimited text (e.g. CSV) and XLS(X)* and write delimited text. But I do plan to add other input/output formats, depending on feedback. I need to think a bit about how to flatten an XML/JSON doc into a table and then turn it back into an XML/JSON doc. (*XLS(X) output currently only works on Windows, because it uses ActiveX. But I plan to have XLS(X) input/output on Windows and Mac at some point.)
