One-time conversion of a set of files/sources (which are similar
format-wise) from one-of XML, CSV, JSON, HTML, EPUB, plaintext (etc.) to
one-of XML, CSV, JSON, HTML, EPUB, plaintext (etc.).
Will learn about the source file(s) and their format, will learn about
the desired target format, and then assess if/how a conversion is
possible, and how (+ why) easy/complex a conversion will be.
