If you have access to both the COBOL source (probably a copybook file) and a Microfocus compiler, you could write an application to convert the data to text files.
Pervasive software's
Parser series is probably the cheapest and easiest way to get to this data. In this case both cheap and easy are relative!
Microfocus' XDBC might be another choice, although I haven't had any experience with it myself.
